Prove thatsin theta(1+tantheta)+costheta(1+cottheta)=sectheta + cosectheta |
|
Answer» LHS=sin theta (1+sin theta /cos theta) +cos theta (1+cos theta /sin theta)=sin theta /cos theta (sin theta +cos theta) +cos theta /sin theta (sin theta +costheta)=( sin theta +costheta) (sin theta /cos theta +cos theta /sin theta)=sin theta +costheta /sin theta *costheta)=1/cos theta +1/sin theta=sec theta+cosec theta=RHS(proved)Hope this will help you ☺️ Brain is the part of our body inside our head that controls our thoughts feelings and movements.??? What is brain |
