In[ ... x cos x dx = =xsinx - sinxol dx = sinx + cosx t до go g=sinx check (xsinx+ COSX SXX COSX x. = 1·. √ x sinx dx = x(-cosx) - S-cosx-1 dx = -x cos x + Scosx doc. The integration of sin x cos x yields (-1/4) cos 2x + C as the integral of sin x cos x using the sin 2x formula of trigonometry. 1). Equivalent form of (Sinx + cosx) / (cosecx tanx +secxcotx 2). If A =sinx and B = Cos x, then the equivalent value of A^2-B^2 is 3). If Tan A tanx = sinx/cosx. This identity can easily be shown by asking the student to draw a right-angled triangle, with one of the remaing two angles labelled x.
