If `xcostheta/a + ysintheta/b =1 ` and` xsintheta/a - ysintheta/b =1 `then

If x costheta-ysintheta=a and xsintheta+ycostheta=b , then prove that x^2+y^2=a^2+b^2 .

If xcostheta+ysintheta=a" and "xsintheta-ycostheta=b," where "theta" is a parameter, then (d^(2)x)/(d theta^(2))(dy)/(d theta)-(d^(2)y)/(d theta^(2))(dx)/(d theta)=
