" 6."log cos x

log {log (cos x}

Prove that: log sin 8x = 3 log2+log sin x+ log cos 2x+log cos 4x

derivative of log {log (cos x}

derivative of log cos x

int sin2x.log cos xdx is equal to 1) cos^(2)x((1)/(2)+log cos x)+k 2) cos^(2)x*log cos x+k 3) cos^(2)x((1)/(2)-log cos x)+k 4) cos^(2)x+log cos x+k

If (cos x)^y = (cos y)^x then show that (dy)/(dx) = (y tan x+log cos y)/(x tan y+log cos x).

int e^("log "x) cos x dx =

Prove that: log sin8x=3log2+log sin x+log cos2x+log cos4x

If int (f(x))/(log cos x) dx = - log(log cos x) + C , then f(x) is equal to a)tan x b) -sin x c) -cos x d) -tan x
