Prove that y 4 sin x/2+cos x
WebbThe parametric equations of a curve are x = 2 t − sin 2 t, y = 5 t + cos 2 t, for 0 ≤ t ≤ 2 1 π. At the point P on the curve, the gradient of the curve is 2. By first expressing 2 sin 2 t 4 cos 2 t in the form R sin (2 t α), where R > 0 and 0 < α < 2 1 π, find the coordinates of P. Give each coordinate correct to 3 significant figures.
