If `y=(log)_(sinx)(tanx)` , then `(((dy)/(dx)))_(pi//4)` is equal to.......

If y=log_(sinx)(tanx), then (dy)/ (dx) at x=(pi)/(4) is equal to

If y=log_(sinx)(tanx), then (dy)/ (dx) at x=(pi)/(4) is equal to

If y=(log)_(sinx)(tanx),t h e n(((dy)/(dx)))_(pi/4)"is equal to" (a) 4/(log2) (b) -4log2 (c) (-4)/(log2) (d) none of these

If y=(log)_(sinx)(tanx),t h e n(((dy)/(dx)))_(pi/4)"is equal to" (a) 4/(log2) (b) -4log2 (c) (-4)/(log2) (d) none of these

If y=(log)_(sinx)(tanx),t h e n(((dy)/(dx)))_(pi/4)"is equal to" (a) 4/(log2) (b) -4log2 (c) (-4)/(log2) (d) none of these

If y=log_(sinx)(tanx), then (dy)/ (dx) at x=(1)/(4) is equal to

If y=log_(sinx)(tanx), then (dy)/ (dx) at x=(1)/(4) is equal to

If y=x^(cosx)+(sinx)^(tanx) , find (dy)/(dx)

If y=tanx then (dy)/(dx) at x=(pi)/(4) is equal to:
