Question

the period of|cosx| is​

Answer 1

Step-by-step explanation:

The period of a periodic function is the interval of x-values on which the cycle of the graph that is repeated in both direction lies. Therefore, in the case of basic cosine function, f(x)=cosx, the period is 2π.

The arccosine of x is defined as the inverse cosine function of x when -1≤x≤1. When the cosine of y is equal to x: cos y = x. Then the arccosine of x is equal to the inverse cosine function of x, which is equal to y: arccos x = cos-1 x = y.

What is cos x sin?

cos(x)sin(x)+sin(x)cos(x)=sin(2x) But since we multiplied by 2 early on to get to that, we need to divide by two to make the equality, so. cos(x)sin(x)=sin(2x).2
