I was firstly asked to graph the functions y=sinx, y=cosx and y=tanx. My question is to find the points of intersection of where those lines cross. We know that (sinx)/ = cosx and (cos x)/ = -sinx. (tanx)/ = sinx cos x. /. = top′ z }| {. (sinx)/ bottom z }| { cos x - top z}|{ sinx bottom′ z }| {. (cos x)/. In[16] := tanx∗cosx. In[16] := tanx∗cosx. In[16] := tanx∗cosx.

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. 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. Jun 14, 2007 ...

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. Jun 4, 2015 ... The max value equals root2 and minimum minus root 2. Thence the range is between min and maz. Hence the answer would be from minus root 2to root 2. Oct 18, 2021 ... Given that: sinx + cosx = a (sinx + cosx) 2 = a 2 ⇒ sin 2 x + cos 2 x + 2sinx cosx = a 2 ⇒ 1 + 2sinx cosx = a
