Differentiate with respect to t.
y = a cos(t) + t^2 sin(t)
yo what is a
No clue. That is all im given
okay.
t2 cos(t)+ 2t sin (t) - sin (t)
"a" just denotes some constant.....so
y = acos(t) + t^2sin (t)
y ' = - a sin(t) + 2t sin (t) + t^2 cos(t) =
(2t - a) sin (t) + t^2 cos (t)
Sorry for the late response but I understand now. I didn't even see the product rule between t^2 and sin(t).
