plot z-= 1, z=-1, z%... | Find the area of the region enclosed by $P = 2 - z^2$ and $P z = 0$\nWhen I change the equations to equal $P$. I get $\frac{11}{2} $ However, when I change the equations to equal $z$ I don't get the same answer. Here is my work so far: Change the equations to equal $z$: $z=\pm 1$ Change the equations to equal ... |How are these triangles similar?\nI am trying to understand a proof of Pythagorean's Theorem. I am trying to see how all three triangles are similar. So far I have: (1 - Wolfram|Alpha
