If `x=acostheta,y=bsintheta` , then `(d^2y)/(dx^2)` when `theta=pi/4` is given by

If x=acostheta,y=bsintheta," then"(d^(3)y)/(dx^(3)) is equal to

If x=acostheta,y=bsintheta," then"(d^(3)y)/(dx^(3)) is equal to

If x = a sec theta , y =b tan theta , then (d^2y)/(dx^2) at theta = pi/6 is :

If x=asec^3theta,y=atan^3theta, find (d^2y)/(dx^2) at theta=pi/4

If x=sintheta,y=sin^(3)theta then (d^(2)y)/(dx^(2)) at theta=(pi)/(2) is . . .

If x = sin theta, y = sin^(3) theta then (d^(2)y)/(dx^(2)) at theta = (pi)/(2) is …….

1. If x = at ^(2) , y = 2 at then (dy)/(dx) at t =1 is A 2 If x =cos theta, y = sin theta then (dy)/(dx) at theta = (pi)/(4) is B 3 If x =1 - cos theta, y = sin theta , then (dy )/(dx) at theta = (pi)/(6) is C 4 If x = log sin theta, y = tan theta then (dy)/(dx) at theta = (pi)/(4) is D. The ascending order of A,B,C,D is

If x=asec^(3)theta,y=atan^(3)theta then find (d^(2)y)/(dx^(2)) at theta=pi/4 .

If x=acostheta , y=bsintheta , show that (d^2y)/(dx^2)=-(b^4)/(a^2y^3) .

If x = a sin^3 theta, y = a cos^3 theta , find (d^2y)/(dx^2) at theta = pi/4
