If `x=acos^(3)theta and y = bsin^(3)theta`, prove that `((x)/(a))^(2//3)+((y)/(b))^(2//3)=1.`

If x = a cos ^(3) theta and y = b sin ^(3) theta , then the value of ((x)/(a))^(2//3) + ((y)/(b))^(2//3)

If x=acos^(3)theta,y=bsin^(3)theta then ((x)/(a))^((2)/(3))+((y)/(b))^((2)/(3))=?

If x=acos^(3)theta and y=asin^(3)theta , then (dy)/(dx)=

x=a cos^(3)theta,y=b sin^(3)theta : ((x)/(a))^(2/3)+((y)/(b))^(2/3)=1

If x=acos^3theta and y=asin^3theta . Prove that 1+(dy/dx)^2=sec^2theta .

If x = acos^(3)theta , y = a sin^(3)theta ,then find (d^2y)/dx^(2)
