WebFor example, here’s how you integrate. Peel off a sin x and place it next to the dx: Apply the trig identity sin 2 x = 1 – cos 2 x to express the rest of the sines in the function as cosines: Use the variable substitution u = cos x and du = –sin x dx: Now that you have the function in terms of powers of u, the worst is over. WebOct 31, 2015 · Since the unit circle is in a cartesian coordinate system, this must mean they have the same x -coordinates. The first point has an x -coordinate of cos(θ), and the second has an x -coordinate of cos( − θ), and they must be equal, so it quite easily follows that: cos( − θ) = cos(θ) Which proves that cosine is an even function.
