So, you have:
My next step would be:
Now, rationalize the denominator of the argument of the log function on the right.
Hi all,
I'm really stuck on a question and hoping someone can point me in the right direction.
By using the logarithm expression of sinh^{-1}(y), show that sinh^{-1}(-y)=-sinh^{-1}y
So far im at
sinh^{-1}(-y)=ln((-y)+sqrt((-y)^{2}+1))
Thanks
