Find all solutions of the equation. (Enter your answer in the form a + bπn, where a [0, 2π), b is the smallest possible positive number, and n represents any integer. Round a to four decimal places.) cos(x)=-1
cos(x)=-1 thus x=arccos (-1)=180=π also, cos(x)=-1 when: x=π,3π,5π,...... The above is a sequence that can be modeled by: xn=(2π+nπ) where, n=1,3,5,....(set of all odd numbers)
