(e^x+e^-x)/2 or something?:{
Only thing I remember from FP2 tbh. I looked at the textbook once, on the metro on my way to the exam.
Coshx =(e^x+e^-x)/2
Sinhx =(e^x-e^-x)/2
amirite? I need to resit this module having studied it at some point.

Quite right!cosh is also the shape a uniformly loaded washing line would take - ie constant sock density
