Given polar equation is
for polar equation we use
and
plug the given value of r into these equations we get:
find derivative with respect to theta
now slope is given by formula
plug the above values into slope formula and the given angle theta = pi/2
plugging theta=pi/2 and simplifying it gives
m=0.5
Hence final answer is m=0.5
