3. Sketch the curve with polar equation r = cos(30), 0≤ 0 < 2π, plotting only the

1 Sketch the curve r=-+sin0 cos 0 ,0 < 0<2n in the polar plane.

2.Make a sketch of the following polar equation: r = 2 +4 sin 0 (r, 0). Determine also the tangent gradient of the polar curve at the point with 0 = "/2

The slope of the line tangent to the polar graph r = 0 at the point where 0 = 1 is:
