hyperbolic function , relation with ordinary trigonometric functions , identities

hyperbolic function , relation with ordinary trigonometric functions , identities

hyperbolic functions usually refers to relations involving the exponential functions e^x and e^(-x).
They are denoted by functions like sinh(x) pronounced something like shine(x),  cosh(x), tanh(x) , cosech(x), sech(x), coth(x) etc. The relationship with ordinary trigonometric functions and some identities involving hyperbolic functions is given below.



sinh(0)  = 0

cosh(0)  =1

tanh(0)  = 0

Find p If Two Lines Are Perpendicular | 3D Geometry Solution

 If the lines (x - 3)/1 = (1 - y)/1 = (z + 2)/p and (2 - x)/3 = (y + 1)/5 = (z + 56)/2p are perpendicular to each other, then find the value...
