anyone know how to answer these questions using matlab

a = 13;

c = 17;

k = 2*pi/3;

theta = 0:0.0001:2*pi;

b = a*cos(theta) + sqrt(c^2 - a^2*sin(theta).^2)

db/dtheta = - a*sin(theta) - (a^2*cos(theta).*sin(theta))./(c^2 - a^2*sin(theta).^2).^(1/2)

Using your answers to the previous items, determine the angle θ when the shaft is moving at its fastest. What is that largest speed?

How many seconds does it take for the contraption to return to its original state?
