" 6.If "x=a cos^(3)theta" and "y=b sin^(3)theta," prove that "((x)/(a))^(2/3)+((y)/(b))^(3/3)=1

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

x=a cos^(3)theta and y=a sin^(3)theta then :-

If x=a cos^(3)theta,y=b sin^(3)theta, then

If x=a cos^(3) theta , y= a sin^(3) theta then

x=a cos^(3)theta,y=a sin^(3)theta

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

Find the blanks. (i) If x=a cos^(3)theta,y=b sin^(3)theta then ((x)/(a))^(2/3)+((y)/(b))^(2/3)=ul(P) (ii) if x=a sec theta cos phi,y=b sec theta sin phi and z=c tan theta then (x^(2))/(a^(2))+(y^(2))/(b^(2))-(z^(2))/(c^(2))=ul(Q) (iii) If cos A+cos^(2)A=1 ,then sin^(2)A+sin^(4)A=ul(R)

If x=a cos ^(3) theta and y = a sin^(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 = a cos^3 theta, y = b sin^3 theta , then
