jim_thompson5910 · Answer

From the pythagorean theorem, we know

$$\Large a^2 + b^2 = c^2$$

$$\Large x^2 + y^2 = 25^2$$

$$\Large y^2 = 625-x^2$$

$$\Large y = \sqrt{625-x^2}$$

jim_thompson5910 · Answer

What do we get when we derive both sides of $$\Large y = \sqrt{625-x^2}$$ with respect to t? Think of x as a function of t.

hi sorry i logged out last night and didn't see this!
