`{sinx/((1+cosx))+sinx/((1-cosx))}=?`

(sinx)^(cosx)

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)

If sum of the series 1+x log_(|(1-sinx)/(cos x)|)((1+sin x)/(cos x))^(1//2)+x^(2) log_(|(1-sinx)/(cosx)|)((1+sinx)/(cosx))^(1//4)+...oo (wherever defined) is equal to (k(1-x))/((2-x)) , then k is equal to

d/dx((1-cosx)/sinx)=

d/dx((1-cosx)/sinx)=

int(x-sinx)/(1-cosx)dx

int(x-sinx)/(1-cosx)dx

Evaluate : int(sinx)/((1-cosx)\ (2-cosx)\ dx

int(dx)/((sinx-2cosx)(2sinx+cosx))
