I agree with the values you have for where the graphs intersect, but the graph looks a little off. It's hard to be sure however because you didn't put units on the axes. The maximum value of the cosine function is 1 and the minimum value is 1. Thus the bottom of the two valleys in your graph should be 1 unit below the xaxis. The horizontal line y =  0.5 should be half way between the xaxis and the bottom of the valley. Your line is too close to the xaxis. If this is a homework assignment then before you turn it in you should put units on both the x and y axes. Penny
