Let's solve and identify which function is greater, Cos (Sin x) or Sin (Cos x).
Trignometric functions are difficult to SOLVE if you don't know their properties and some basic formula.
Here, we have solved the entire problem by just using 1 basic formula i.e.
Cos C + Cos D = 2 Cos ((C+D)/2) . Cos ((C-D)/2)
Watch the video to understand the real concept to solve this problem.
