Question

Hyperbolic function

medal

Answer 1

i know you use cosh^2 x - sinh^2 x = 1

Answer 2

but how?

Answer 3

you may find `coshx` value using above relation

Answer 4

then use tanhx = sinhx/coshx ?

Answer 5

so just sinh7/coshx ?

Answer 6

guess so..

Answer 7

err..

Answer 8

we need to find coshx value first haha

Answer 9

cosh^2 x - sinh^2 x = 1

cosh^2 x - 7^2 = 1

cosh^2x = 1+7^2 = 50

\(\large \cos hx = \pm 5\sqrt{2}\)

Answer 10

\(\large \tan hx = \dfrac{\sin hx}{\cos hx} = \pm \dfrac{7}{5\sqrt{2}} \)

Answer 11

try entering that ^^

Answer 12

yup works. that makes more sense. thanks
