If `x=atan theta and y=b sec theta` then

x =a tan theta ,y =b sec theta

Evaluate (y^(2))/(b^(2))-(x^(2))/(a^(2)) , whre x=a tan theta and y= b sec theta .

Evaluate (y^(2))/(b^(2))-(x^(2))/(a^(2)) , where x= a tan theta and y = b sec theta

If x=a sec theta and y=b tan theta then b^(2)x^(2)-a^(2)y^(2) =_____.

If x=a(sec theta + tan theta)^(2) and y=b(sec theta- tan theta)^(4) , then x^(4)y^(2)=

If x sec theta + y tan theta = a, x tan theta + y sec theta = b " then " a^(2)-b^(2) =

If theta is eliminated from the equations a sec theta-x tan theta=y" and "b sec theta+y tan theta=x (a and b are constants), then :

If a=x sec theta + y tan theta , b = x tan theta + y sec theta then x^(2)-y^(2)=
