What does cosx sinx equal? | Socratic cos(x)sin(x) = sin(2x)/2 So we have cos(x)sin(x) If we multiply it by two we have 2cos(x)sin(x) Which we can say it’s a sum cos(x)sin(x)+sin(x)cos(x) Which is the double angle formula of the sine cos(x)sin(x)+sin(x)cos(x)=sin(2x) But since we multiplied by 2 early on to get to that, we need … Continue reading “cosxsinx=”
