Show that equations `x=a cos theta + b sin theta, y = a sin theta - b cos theta` represents a circle, wheter `theta` is a parameter.

Show that : x=a cos theta - b sin theta and y = a sin theta + b cos theta , represent a circle where theta is the parameter.

If a cos theta - b sin theta =c, " then" a sin theta + b cos theta 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

what is the relation between a cos theta+b sin theta=p and a sin theta-b cos theta=q

if theta is a parameter then x=a ( sin theta + cos theta), y=b( sin theta - cos theta ) respresents

Prove that : x cos theta + y sin theta = a and x sin theta - y cos theta = b are the parametric equations of a circle for all theta satisfying 0le thetalt2pi
