x=3 cos^2 t y= sin 2t, 0 ≤ t < pi
I need to find coordinates of the points where the tangent to the curve is parallel to the x axis. How would i go about doing this?
Is this the stationary point?
therefore dy/dx =0?
However, how would i go about solving this? (really poor i know... it's C2, C3 stuff, i've forgotten...)
