Web18 okt. 2015 · Use the fact that $\sin 61° = \sin (60°+1°)$ to give an approximate value of $\sin 61°$ in terms of $\pi$. My textbook says that the answer is $ (180\sqrt (3)+\pi)/360$, but I don't understand how it got there. I can expand the identity of $\sin (60°+1°)$ but I don't know where to go after that. calculus trigonometry approximation Share Cite Follow WebThe value of sin30.cos60+cos30.sin60 is Easy Solution Verified by Toppr Step-1: Using Formula sin (A + B) = sinA.cosB + cosA.sinB …(1) Here A = 30, B = 60 Step-2: Putting values of A and B in (1) sin (30 + 60) = sin30.cos60 + cos30.sin60 sin (90) = sin30.cos60 + cos30.sin60 1 = sin30.cos60 + cos30.sin60
