Online Graphing


Please go to the following website: http://rentcalculators.org/stheli.html and practice typing in a few of last night's homework problems. When you first get to the webpage, please click the link that says "Free Online Graphing Calculator"


After exploring the grapher, critique the online grapher.


In your critique, you must include

- your recommendation - should other students use this website EXPLAIN why you do or don't recommend this as a resource.

- 3 things you liked about using the online grapher

- 3 things you did not like about the online grapher

- hints or tricks you discovered.

THEN. You must graph one homework problem, copy the screen by hitthing the "PRINT SCREEN" and pasting the screen in a word document. Please indicate on the word document which problem from homework you graphed, include your name and print the page.

I must ok your page before you print!

3 things i liked about the online graphing calculator:
- you can change the colors of the lines
- you can make parallel lines
- it was easy to figure out

3 things i didnt like about the online graphing calculator:
-????
-????
-????

hints or tricks i discovered were:
- i found out that if you make parallel lines and hit point of intersection it will tell you "no solution"

i like using the online caculater because it is simple and easy to find the answer to the problem your looking for.

I reccomend the online graphing calculator because it is helpful and a way for students to learn how to use different types of calculators.

Like:
1-different colors
2-bunch of things that help us learn better
3-easier than working problems out by hand.

Dislike:
1-not use to it yet
2-a little confusing
3-you had to keep clicking a lot of parts to get to where you are going.

Critique-

I would recommend this to other sutednts b/c it's very helpful. When someone doesn't have a graphing caculator at home,or downloaded onto their computer then they could just use this website.I like how you can find the intersection by just hitting the "Intersection" bar at the top. This online caculator is just as useful as the one we have at school. There's nothing that i don't like about this online caculator.

i did not find out any tricks or hints to help me use the online graphing calculator better.

3 things like-
*different colors for the
show us how the line will look
put any equation in and

3 dislikes-
*click a lot of buttons just to get what you want
*not used to it yet
*confusing

Tricks: If you plot parrell lines it will tell you no solution

dear ms .nelson,
3 things that i liked about the calculator were: the different colors the you can change, that it would graph any problem you typed in, and that you could zoom all the way out and all the way in and all the way out. 3 dislikes were: that you had to change the settings every single time in order for your graph to be accurate, you had to click a lot of links to graph your equations, and the whole process takes too long. a trick that i discovered is that the graph stays the same no matter how far you zoom out. another trick is that you can change the colors of the lines to see the difference.

The calculator graphing was okay three things that I liked was that it helps on problems you can't do at school and can help u alot on the homework.One thing i did not like was that it takes too long to put in the numbers .

About the free calculator download site, I think more students should use it. It was WAY easier than using the calculator, because you have to press all kinds of buttons to get there, not to mention how small the writing is.
I liked the online calculator because:
1. You can change the color of your graph.
2. It gives you the Intersection points in one easy click of a button.
3. The site made it fun to graph.
I DIDNT like the online calculator because:
1.The settings were a little confusing.
2. If you typed in a wrong number, you got the equation wrong.
3. It was a little bit hard to figure out what buttons to push.

Some tricks I figured out were:
* If you press the little eye button beside the colors(only works if you have more than 1 equation) then it will take away those graphs!!!!

Overall it was fun!!

This is so fun yet it is also edecational because seriously would you be doing work out of a text book or do something that would actualy be a little fun??!!!

I recommend that other kids use the online graphing calculator because it's easier to use and because you can change the colors of the graph.
I liked everything about the online calculator especially because it's easier to handle. There was nothing i disliked about the calculator everything was perfect.

i would definetly recommend this program for anyone who struggles with graphing their equations. also this could be a reliable website for homework.

the calculator that the website lets you use is alright. its only purpose is to let you graph so that means that you cant really do any math problems or equations on it. i would say that it is not a good calculater to use at home unless thats all your doing(graphing). but it is great at graphing so its not all that bad.

3 things that i liked abou the online calculator:
#1: you can change the colors like Maddie said.
#2: it was easy to figure out.
#3: you can find the intercepts quick and easy.

3 things that I don't like about the calculator:
#1: I do not know.
#2: I do not know.
#3: I do not know.

hints or tricks i found out were that you can find the intersection very easy by just clicking on the top tool bar were it said intersection than on your points and then you have your intercepts.

3 things i liked about this calculater was..........
~diferent colors
~you can do different things with it
~so much cooler than the regular calculator
there wasnt anything I didnt like about this
A trick I learned was if the lines should intersect but dont zoom out and it will show the intersecting lines.

i liked the fact that it was quick and easy, the colors that it incorporated, and the zoom in and zoom out icon. however i disliked the fact that you weren't allowed to do math on it, the small amount of colors, and the fact that it took me forever just to zoom in and zoom out.

i would recommend this as a rescource because it is free and does everything a calculator does.

what i liked:
>lines were in seperate colors
>you could zoom in or out
>you could find the intersection

what i didn't like:
>you couldn't hold the zoom button
>it wasn't on a grid
>it didn't round the intersection point.

hints or tips:
>dont zoom in or out too much

there were many aspects that grabbed my attention although there was one thing that really grabbed my attnetion. this occurred while keenan and i were just playing around with the calculator and when we typed in the equation (-x+ a constant) four times it created what we call a "Laser Beam Show!"

I like the program because it is easy to type the equqtions. And it doesn't take long at all. I like how the lines changed colors too. There was nothing i didn't like about it everything was fine to me. This would be a great resource for people who have trouble graphing by hand.

I recommend dis website 2 pplz that need a calculator at home becuz they r in need of help. I think otha students should use dis website 2 because it a really fun way 2 use a calculator especially when they need help with graphing. Also becuz we get stuck on some questions that deals with graphing on Math hmwk. and b wanting 2 guess or skip it. Plus not all people have calculators at home n when they do got 1, they don't have graphing in it. So it really helps somebody out when they do got internet on their computers or laptops.

3 things I like abt using da online grapher is...

*that we can pick what color we want da lines (that way we don't get confused with da lines n da equations)
*It's easy 2 understand it n how 2 use it.
*It can find da intersection of lines n we can pick how we want da Y n X axis.

There wasn't nothing I didn't like abt it. It seems pretty cool 2 mi.

3 thinggs i liked about the grapher are

you can change the colors of lines

you can change how big the graph is

you can type in all kinds of equations and it will solve them!!


3 things i didnt like..

there werent many colors to choose from

the zoom feature wasnt very effective

i cant think of anything else...

cool trick i found out is when u zoom in far enough, u get lots of lines the same color as the one big line on normal projection.

There's nothing wrong with it.
This would be great for someone who can't graph well or who wants things done quick. I didn't find any hints or tricks, but it was very easy to use.

3 things i liked about the Online Calculator:

1.) Graphs lines that you can't
2.) Has different colors for lines
3.) ???

3 things i didn't like:

1.) Had to zoom in/out to see all lines
2.) For some lines, no intersections
3.) ???

Hints or tricks found:
- if you make 2 lines equal, then find the intersections, it will say "No intersections."

Anonymous said...

I think this calculator is awsome!
I say others should use this site because it could help us with graphing two linear equations.
I liked the fact you can change the colors of the lines. Also I like how you can see the lines clearly.
