E. e3x ... sin x > cos x on the interval 0 x < 2 . From the unit circle we see that sin x and cos x can only have the same value in two places, in x = ... sinx = cosx tanx = 2t. 1+t2 . Write I = / a. 0 dx. 1+cosx+sinx . Since dt/dx = sec2. (x/2). 2. = (1+t. 2. )/2, we see that. I = ∫ tan(a/2). Given the trigonometric identity as It can be verified by expanding and simplifying the left hand side as follows. Jan 14, 2017 ... Proof by contradiction: sin(x)−cos(x)≥1 · Perhaps simpler is to consider that cos(x+π4)=1√2(cosx−sinx) and manipulate this expression a bit. – ... Start with the definition of the logarithm function: Hence, Let Substitute back, recalling that the sine function is positive in the first quadrant.
