View question - 2 sinx cosx = sin x

Originally Answered: Why sin(-x) =-sinx and cos(-x) =cosx? This occurs because cos x is an even function, meaning, for any f(-x)=f(x), the function is an even function, while sin x is an odd function, where f(-x)=-f(x){in both the cases, x belongs to R}. You can also verify this using the trigonometric...Решение задачи 10.Решить неравенство cos. Яна Снежная.
