can someone please show the steps for both of these questions please. thanks !!

5. When the graphs of two functions intersect the angle of intersection is defined as the angle between their tangents at the point of intersection. Consider the following functions y = Asinx and y = (E + F)cos2x. [Show all steps for FULL marks] a) Determine the point of intersection of the curves algebraically for 0 S x 5 5. E = 8 F = q b) Determine the slopes of the tangents to the curves at the point of intersection. /8
