Sinh (2Lnx)
Solve for x over the real numbers: sinh(2 log(x)) = 0
Take the inverse hyperbolic sine of both sides: 2 log(x) = 0
Divide both sides by 2: log(x) = 0
Cancel logarithms by taking exp of both sides: Answer: |x = 1
sinh(2ln x)
= \(\dfrac{1}{2}(e^{2\ln x}-e^{-2\ln x})\)\(\text{<----By definition}\)
=\(\dfrac{(e^{\ln x})^{2}}{2}-\dfrac{1}{2(e^{\ln x})^{2}}\)
=\(\dfrac{x^2}{2}-\dfrac{1}{2x^2}\)
