Question

The equation `costheta=1/2` from `0<=theta<2pi` has solutions `pi/3` and `(5pi)/3`. What is the general solution corresponding to `pi/3`?

Answer 1

`pi/3 + 2pin`

Explanation:

The function `y = cosx` has a period of `2pi`.

Therefore, the general solution of any equation in cosine will have `+ 2pin` where n is an integer.

Hopefully this helps!
