If 3tanhx = 1 ,determine exact values of sinhx and coshx.
Can anybody help with this one!
The ans is,
1/(2(sqrt 2)) and 3/(2(sqrt2))
Well, first you'd need to move the 3 to the other side and then take the inverse:
There is a formula for solving the arctanh, and that is:
Plugging in u = 1/3, you get:
This ends up being:
Plug this into sinh and cosh to get:
That checks out with the answer.
This also checks out.
Hope this helps!
