Find all solutions to the equation. cos x = -one divided by two

x = 2πn - π/3

x = 2πn + π/3

Step-by-step explanation:

Given that a trigonometric equation

cos x =

We know that,

cos x = -

Now take the inverse of cos both the side

x = -π/3

We know that, the cycle of cos is 2π

So, we add 2πn where n is any integer.

x = 2πn - π/3

x = 2πn + π/3

That's the final answer,

I hope it will help you.
