Question

if x sin^3theta+ y cos^3theta =sin theta cos theta and x sin theta =y cos theta, prove that x^2+y^2=1​

Answer 1

Step-by-step explanation:

x sin^3theta+ y cos^3theta =sin theta cos theta

x sin theata×sin^2theta+ y cos^3theta =sin theta cos theta

ycos theata sin^2theta+ y cos^3theta =sin theta cos theta
