Question

An object is moving in the plane according to these parametric equations:
x(t) = πt + cos(4πt + π/2)
y(t) = sin(4πt + π/2)
A portion of the "cycloidal" path (on the time interval [0,1])
The slope of the tangent line to the path at time t is?

Answer 2

okay so

Answer 3

u have ur vector
r(t)=<x(t),y(t)>
