11. 18. · If you want you can start from : sin^2 x + cos^2 x = 1 Divide through by cos^2 x to get: (sin^2 x)/(cos^2 x) + 1 = 1/cos^2 x = tan^2x + 1 = sec^2x The power reduction formula: cos^2 x = (1 + cos 2x)/2, 2cos^2x = 1 + cos 2x Now, your problem: 1 + cos 2x = 2/(1 + tan^2 x) Using the fact that: sec^2x = 1 + tan^2x 1 + cos 2x = 2/(sec^2 x) 2 cos^2 x = 2/(1/cos^2 x) 2cos^2 x = 2cos^2 x Which proves integrate x/(x-1) integrate x sin(x^2) integrate x sqrt(1-sqrt(x)) integrate x/(x+1)^3 from 0 to infinity; integrate 1/(cos(x)+2) from 0 to 2pi; integrate x^2 sin y dx dy, x=0 to 1, y=0 to pi; View more examples » Access instant learning tools.
