If x = a cos3 θ and y = a sin3 θ, then find the value of at .

Given: x = a cos3 θ and y = a sin3 θ


To find:




x = a cos3 θ


Differentiating both sides with respect to θ:








y = a sin3 θ


Differentiating both sides with respect to θ:












Differentiating both sides with respect to x:
