यदि `x=a cos theta +b sin theta. Y= a sin theta -b cos theta` तब सिद्ध कीजिए कि `y^(2)y_2-xy_1+y=0`

x = a cos theta, y = b sin theta .

If x cos theta + y sin theta = a , x sin theta - y cos theta = b then

If x/a cos theta + y/b sin theta = 1 , x/a sin theta - y/b cos theta = 1 then x^2/a^2 + y^2/b^2 =

If x=a cos theta + b sin theta and y=a sin theta - b cos theta. then a ^(2) +b^(2) is equal to

If x=a cos theta + b sin theta and y=a sin theta - b cos theta. then a ^(2) +b^(2) is equal to

If a cos theta +bsin theta=x and a sin theta-b cos theta = y then prove that a^2+b^2=x^2+y^2

If x = a cos theta + b sin theta and y =asin theta-b cos theta , then prove that y^2 (d^2y)/(dx^2)-x(dy)/(dx)+y=0

If x = a cos theta + b sin theta and y =asin theta-b cos theta , then prove that y^2 (d^2y)/(dx^2)-x(dy)/(dx)+y=0

If x = a cos theta + b sin theta and y =asin theta-b cos theta , then prove that y^2 (d^2y)/(dx^2)-x(dy)/(dx)+y=0

If x = a cos theta + b sin theta and y=a sin theta-b cos theta , the value of x^2+y^2 is: यदि x = a cos theta + b sin theta तथा y=a sin theta-b cos theta है, तो x^2+y^2 का मान ज्ञात करें |
