    slope of tangent

    Let C be the curve in the plane defined by r=2+sin\frac{1}{2} \theta . Calculate the slope of the tangent of C when \theta = 0 and when  \theta=2 \pi . The formula  \frac {dy}{dx} = \frac {\frac {dy}{d \theta}}{\frac {dx}{d \theta}} may be helpful.

    Ok so using that formula i get 4 and -4 for the slopes when \theta = 0 and when  \theta=2 \pi respectively. It just seems quite easy so I wanted to check if I didn't overlook something. Can anyone confirm that?
