If `sinx/a=cosx/b=tanx/c=k` and `bc+1/(ck)+(ak)/(1+bk)=?`

If (sin x)/(a)=(cos x)/(b_(k))=(tan x)/(c)=k, then bc+(1)/(ck)+(ak)/(1+bk) is equal to k(a+(1)/(a)) (b) 1/k(a+(1)/(a))(1)/(k^(2))(d)(a)/(k)

sinxtanx-1=tanx-sinx

sinxtanx-1=tanx-sinx

Solve sinx+cosx=1+sinx.cosx

int(tanx)/(1+cosx)dx=

If y=(sinx +cosx )^((1+tanx )),then (dy)/(dx) =

Prove that: tan^(-1){(a cosx-b sinx)/(b cosx+a sinx)} =tan^(-1)((a)/(b))-x

If y=(sinx)/(1+(cosx)/(1+(sinx)/(1+(cosx)/(1+ tooo)))),p rov et h a t(dy)/(dx)=((1+y)cosx+ysinx)/(1+2y+cosx-sinx)

If y=(sinx)/(1+(cosx)/(1+(sinx)/(1+(cosx)/(1+ ddotto oo)))) , prove that (dy)/(dx)=((1+y)cosx+ysinx)/(1+2y+cosx-sinx)
