# How do you find the intersections points of y=-2cosx and y=3sin(3x)?

As this question is in the "Graphing Trigonometric Functions" section, I assume that the graphical solution is preferred over the numerical one of $- 2 \cos \left(x\right) = 3 \sin \left(3 x\right)$. You can expand a graph scale to find individual solution points. As both functions are continuous there are an infinite number of intersections.
