Webif 3sin theta + 5 cos theta =5. then find the value of 5 sin theta -3 cos theta. Rhinithaa PT, 11 years ago Grade:11 4 Answers Tushar Makkar 37 Points 11 years ago ur ans. is -3 watch such type of questions are very easy . i solved this ques. in a fraction of sec. WebIn the approach shown in the question, you convert the cosine to a sine. Suppose instead you convert the sine t a cosine: $$ \sin(m\theta) = \cos\left(\frac\pi2 - m\theta \right).$$ laura luotola paha poika
