If `x=a(theta+sin theta), y=a(1-cos theta)`, then the value of `(dy)/(dx)` is -

If x = 2(theta + sin theta) and y = 2(1 - cos theta) , then value of (dy)/(dx) is

If x = 2(theta + sin theta) and y = 2(1 - cos theta) , then value of (dy)/(dx) is

If x=a cos theta, y=a sin theta , then the value of (dy)/(dx) is -

If x=-a(theta-sin theta),y=a(1-cos theta), then (dy)/(dx) is

If x=a(theta+sin theta), y=a(1-cos theta) then show that (dy)/(dx)=tan(theta/2) .
