The a and b determine how big or small the shape of the conic section is. 
<span>For the different conic sections given through the equations </span>
<span>Circle: x^2/a^2 + y^2/a^2=1 </span>
<span>Ellipse: x^2/b^2+y^2/a^2 = 1 </span>
<span>Hyperbola: x^2/a^2 - y^2/b^2 = 1 </span>
<span>When trying to isolate cos and sin from those equations to get cos^2t + sin^2 t = 1 you can determine the conic section when substituting cos t = x/a and sint = y/b into cos^2t+sin^2t square it and then refer to the conic section equations to determine the conic section. x defines the major axis and y is the minor axis. a and b provide the coordinate pairs</span>

Hello! Any theater kids out there? if so, Please write me a 3-4 sentence long monologue.
Gnom [1K]

Answer:

      A student is sitting at a desk, getting ready for a math test.

Oh...no…I’m in big trouble. In all the days, why today do we have to have a pop quiz in math? I didn’t EVEN study! I just hate math! Ever since I started algebra, math has gotten harder and harder! Every time I look at an equation, the numbers get all mixed up and jumbled in my brain, and I try to remember the way to solve the problem. And by the time I find out how to solve that problem, HALF of the class is already DONE! But today might be a different day. Like they say, if you believe in yourself, anything is possible. Oh,no, Mr. Boyd is coming! (The teacher places the quiz in front of her/him.) (She/he looks at the quiz.) Oh, this doesn’t look half as bad. Ok, if  two x plus fifty equals four x plus nine, then you bring the two over and… oh no! I forgot what you do next! (Sighs) ok, focus, focus. Breathe in, and breathe out.(Sighs) Ok, I got this.(Completes the rest of the quiz without a problem.) Finished! (Teacher comes by to collect his/her work.) Ok, I think I did good. I swear for the REST of my life I will never do a math problem again!

 

Step-by-step explanation:

Hope you like it. I have hard time with Algebra.
