Proving that the derivative of sin(x) is cos(x) and that the derivative of cos(x) is -sin(x). The trigonometric functions sin (x) and cos (x) play a ... 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. Work each problem.Find the exact values of sin x, cos x, and tan x, for x = π/12 , usinga. difference identitiesb. half-angle identities. Detailed Solution ... Solving this, we get b = sinx . Then, a = bcosx sinx = cosx . Therefore, a 2 + b 2 = sin 2 x + cos 2 x = 1 . Hence, the correct option is (2) ... In[16] := tanx∗cosx. In[16] := tanx∗cosx. In[16] := tanx∗cosx.
