1. Show that for sinx+cos x dx = /2 sin x T

1. Show that for sinx+cos x dx = /2 sin x T 2. The German mathematician Karl Weierstrass (1815-1897) noticed that the substitution t = tan will convert any rational function of sin x and cos x into an ordinary rational function of t. It can be shown that COS X = C/2 1-t 1+t2: Show that f sin x = 2t 1+t2, and dx = 2 1+t dt. dx = by making the above substitutions (remembering to also convert the interval of integration) and using techniques of integration discussed this semester. sin x sin x+cos x
