Im kinda working ahead of myself on my assignment and I am stuck on this question:
Solve the following for X
cosh^2(x) + 5sinh(x) + 6 = 1 + sinh^2 (x)
Any help would be great!
Thanks Plato that was a massive help! I knew nothing about hyperbola so I went on to read a bit more after looking at your reply and came up with this which I hope is correct!
(cosh^2(x)-sinh^2(x)0+5sinh(x)=1-6
Using identity (cosh^2(x)-sinh^2(x))=1
1+5 sinh(x) = -5
5sinh(x) = -5-1
5 sinh(x) = -6
sinh(x)=-6/5
sinh(x)=-1.2
sinh^-1(-1.2)=x
x = -1.015973134
