1. parametric question!

Hi, for my math class, I need to write my name into my graphing calculator using parametric equations. I'm using Allie, and I don't know how to create a semi-circle for the 'A', or the 'e'. Also, I'm not sure how to do the 'i', and by that I mean how to make the line shorter and also how to create the dot. Any help would be very appreciated! Thanks!

2. a perfect semi circle can be created with $x(t)=Bcos(t)\ \ y(t)=Bsin(t)$ with $\frac{\pi}{2}\leq t\leq \frac{3\pi}{2}$ that will work for the "e", for the top of an A, you would need to restrict $0\leq t\leq \pi$ and making B a larger number will make the circle bigger

3. Okay thank you, that does help. How do I restrict the in my calculator?

4. depends what kind of calculator you have. The TI-83 onwards have a window button. Other calculators have a similar function.

5. thank you! I forgot about the v-window.
