2x=a cos theta*y=b cos theta

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 x=a cos theta-b sin theta and y=a sin theta+b cos theta then prove that :x^(2)+y^(2)=a^(2)+b^(2)

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

Eliminate theta between the equation : x =a cos theta + b sin theta, y =a sin theta- b cos theta .

x=a sin2 theta(1+cos2 theta), y=b cos2 theta(1-cos2 theta) then (dy)/(dx)=

If =a sin2 theta(1+cos2 theta),y=b cos2 theta(1-os2 theta)x=a sin2 theta(1+cos2 theta),y=b cos2 theta(1-os2 theta) and (dy)/(dx)=k tan theta then the value of k is

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

x=a cos theta+b sin theta and y=a sin theta-b cos theta show that y^(2)(d^(2)y)/(dx^(2))-x(dy)/(dx)+y=0

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