QUESTION

How do you verify ##tanh x/(cosh x - sinh x tanh x) = sinh x##?

see below

Left Side: ##=(sinhx/coshx)/(coshx-(sinhx*sinhx/coshx)##

##=(sinhx/coshx)/(coshx-sinh^2x/(coshx))##

##=(sinhx/coshx)/((cosh^2x-sinh^2x)/(coshx))##

##=sinhx/coshx * coshx/(cosh^2x-sinh^2x)##

##=sinhx/(cosh^2x-sinh^2x)##

##=sinhx/1##

##=sinhx##

##=## Right Side
