Question

find the velocity at t=3π/4
v= 2-2cos2t

Answer 1

translate as "take the derivative, plug in \(\frac{3\pi}{4}\)"

Answer 2

wouldn't taking the derivative of velocity be acceleration?

Answer 3

if that v equation is velocity, then you simply replace t with 3pi/4 and evaluate.

Answer 4

okay I see now with a calculator I couldn't figure it out by hand

Answer 5

what result did you get
