```										Dear Vinod
Hyperbolic sine of x = sinh x = (ex - e-x)/2
Hyperbolic cosine of x = cosh x = (ex + e-x)/2
Hyperbolic tangent of x = tanh x = (ex - e-x)/(ex + e-x)
Hyperbolic cotangent of x = coth x = (ex + e-x)/(ex - e-x)
Hyperbolic secant of x = sech x = 2/(ex + e-x)
Hyperbolic cosecant of x = csch x = 2/(ex - e-x)
using above relation we can draw the graphs

GRAPHS OF HYPERBOLIC FUNCTIONS
y = sinh x
y = cosh x

y = tanh x
y = coth x

y = sech x
y = csch x

All the best.
