If a 30 then sin2a
WebAnswer (1 of 23): By seeing Sin A + Cos A = 1 and knowing that Sin^2 A + Cos^2 A = 1 one would think of solving this analytically. But the best way is to solve this graphically. Because Sin A and Cos A graphs are simple enough and adding them is easy on the graph, our approach is solidified by t... Web29 mrt. 2024 · Transcript.
