2,106. Essentially, you want to solve the equation $\cos (A)=\cos (B)$, or equivalently, $\cos (A)-\cos (B)=0$. By a sum-to-product identity, this is equivalent to 

## Functions: Graphs and Intersections

Then the intersection points of. f(x) and. g(x) are those numbers. x for which. f(x)=g(x). Sometimes the exact values can be easily found by solving the equation. f(x)=g(x)
