Jun 17, 2013 ... for m in range(7,11+1): print 'm=',m print 'Indef_I_m=',integrate(f(m,x),x). And Output: m = 7 Indef_I_m = 1/16*x + 1/16*sin(2*x) + 1/ ... Mar 9, 2022 ... Prove the identity, cos2x/1-sinx = cscx+1/cscx. Note that each Statement must be based on a Rule chosen from the Rule menu. You can see from the graph that cos t = 1 if t = 0 or t = 360. ... 360 = 720, .... That is x = 0, x = 180, x = 360, ... But you only want values of x that satisfy ... • Sketch the graph of y = cos 2x. Sketch a graph of y = 1. 2. + 1. 2 cos ...
