#cos(2x) = cos^2x-sin^2x# # = 1-2sin^2x# # = 2cos^2x-1# To reduce an even power of cosine, use #cos(2x) = 2cos^2x-1# to see that #cos^2x=1/2(1+cos(2x))# So, #int cos^2x dx =1/2int(1+cos(2x))dx# # = 1/2[intdx+int cos(2x)dx]# # = 1/2[x+1/2sin(2x)]+C#. sin^2(x) + cos^2(x) = 1, so combining these we get the equation
