The method of eliminating 'theta' from two given equations involving trigonometrical functions of 'theta' . By using given equations involving 'theta' and trigonometrical identities, we shall obtain an equation not involving 'theta' . On the basis of above information answer the following questions. If sin theta+ cos theta= a and sin^(3)theta+cos^(3) theta=b , then we get lambda a^(3) + mu b+ v a =0 when lambda , mu, v are independent of theta , then the value of lambda^(3)+mu^(3)+v^(3) is
