y = cos`theta` and x = sin`theta` `(dy)/(dx)` at `theta=(pi)/(4)` is :

If y=1- cos theta, x =1 - sin theta,then (dy)/(dx) " at " theta = (pi)/(4) is

If x=sinthetacos2theta,y=costhetasin2theta," then "((dy)/(dx))" at "theta=(pi)/(4) is

If x= e^(theta )(sin theta - cos theta ) , y= e^(theta ) ( sin theta + cos theta ) then (dy)/(dx) at theta =(pi)/(4) is

If x = a (theta + sin theta), y = b (1+ cos theta), then (dy)/(dx)" at "theta = (pi)/(2) is:

If x=2cos theta-3sin theta & y=2sin theta+3cos theta such that (dy)/(dx) at theta=(pi)/(4) is equal to (a)/(b) (where a & b are relatively prime),then |a+b| is equal to

If x = a cos theta and y = b sin theta , find (dy)/(dx)

if x=a cos^(4) theta, y= a sin^(4) theta, "then" (dy)/(dx)"at" theta=(3pi)/(4) is

If x=a(cos theta+log tan((theta)/(2))) and y=a sin theta then find (dy)/(dx) at theta=(pi)/(3) and theta=(pi)/(4)

If x=a(theta-sin theta) and,y=a(1+cos theta) find (dy)/(dx) at theta=(pi)/(3)
