Hint:
Some help in the right direction? I have no idea where to start:
Question:
If sinh x = 3/4, find the values of the other hyperbolic functions at x.
I would greatly appreciate any help! I'm taking a distance course and learning all this by yourself is tough!!

When remembering the differences between the normal trigonometrical functions and their hyperbolic alternatives, I find it useful to use the,
That is, if there are two sinhs multiplied together, as in the , the you change the sign that you would use normally, in this case it is a minus instead of a plus.2 sinhs change the sign.
Thank you to Ruun, flyingsquirrel and Craig for giving me tips to solve;
Question:
If sinh x = 3/4, find the values of the other hyperbolic functions at x.
I have tried solving it using terms of the e^x definitions, and also working through cosh^2 (x) - sinh^2 (x) = 1, but I am not getting anywhere. I'm not sure what to do now, or how much help anyone can give me...
Thanks for reading and posting earlier, any further advice would be wonderful!
cheers
