Start with the definition of the logarithm function: Hence, Let Substitute back, recalling that the sine function is positive in the first quadrant. d) 6 cosx + 5 sin x e) −5 cosx + 12 sinx f) 4 cosx − sin x g) −2 cosx − 3 sin x h) −cosx + 3 sin x i) cosx + sin x j) cosx − sin x k) sin x − cosx l) −(cos x + ... It's correct so far, but I don't think it helped. Expand out the bracket on the LHS and see if you recognize anything. 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)/.
