Differentiatiing Parametric Equations: r(t) = acos(t)i + bcos(t)j

[noobishnoob]

Hi, I have been asked to determine formulas for the velocity, speed and acceleration of the object whose parametric curve is given by:

r(t) = acos(t)i + bcos(t)j

I am confused regarding how to differentiate this properly.

Treat unit vectors i and j as constants.
