x_1=pi/4 and x_2=(3pi)/4 First, take the half over to the other side to get: cos^2(x) =1/2 then square root: cos(x)=1/sqrt(2). We now need to find the inverse of this. If we look at the graph of cos(x) over the given region we see: graph{cos(x) [-0.1,6.15,-1.2,1.2]} We should expect two answers. 1/sqrt(2) is the exact value for cos(pi/4) So we know at least x_1 = cos^-1(1/sqrt2) ->x_1=pi/4 ....
