please that can answer this will get 50 points and I'll mark BRAINLIEST. plot the graph of y= 2cos2x-1 ranging from 0°<x<180°. Use 2cm rep 30° on x axis and 2cm rep 1 unit on y axis. (a) On the same axis plot the graph of y=(1/180)(x-360 ) (b) use the graph to solve the equation 2cos2x-(x/180)+1=0. (c) Find the values of of x for which for which 2cos2x+(1/2)=0. (please a step by step explanation)
