Question

What is cos 0? A. Square root 3B. 1/2C. Square root 3/2D. Square root 3/2

Answer 1

Given the terminal point of the angle θ is as follows:

$(\frac{1}{2},\frac{\sqrt[]{3}}{2})$

The cosine of the angle is the x-coordinates of the terminal point

So, the answer will be:

$\cos \theta=\frac{1}{2}$

The answer will be option B. 1/2
