Answer 1

Answer: shifted by π/2 radians

Explanation:

The function sine of 'x' can be equated to the function cosine of 'x' by shifting cosine by 180 degrees. In math words:

`sin(x)=cos(x-180)`

The value 180 degrees in radians would be π/2. Therefore, in radians:

`sin(x)=cos(x-\pi /2)`

The 'x' inside of the functions is called the argument, and the value added or subtracted to the argument is the phase. The correct answer would be that sine is equal to cosine shifted by a phase of π/2 radians
