# Thread: [URGENT] Math Project - Graphing

1. ## [URGENT] Math Project - Graphing

Hello everybody. I am hoping that somebody can help me. I really really suck in math, and am currently failing. To get my mark up i need to complete a project, but I don't understand what i am doing. Was wondering if I can get some help.

I need to create a picture on my TI-83 graphing calculator using equations. I need help doing this, something simple like a popular logo or a flag. ANYTHING! I really need help and it is appreciated. Thanks to all who reply.

This is really easy. I did a picture of homer simpson... I'd transfer it on here if I knew how. I don't have the equations, but I do have the picture.

Good luck.

Do you have TI-Connect and a USB cable that connects to your calculator? If so, you can upload it....

4. Ive been working on a picture all night here. but i need help with a few equations.

First, this is going to sound stupid, but how do i make a vertical line? I need a line at X = 2

Second, I need a half circle and I dont know how to make one.

Its suppose to be the top half of the sun so it should be

Hight wise between -7 and -10

Length wise between -10 and 10

Im not allowed to use DRAW

It all has to be done with equations, so if anybody could help me with those that would be great.

A half circle of radius r is made by $\displaystyle \sqrt{r^2-x^2}$
