    Finding the inverse of function

    since we want to get rid of sinh, do we take the inverse sinh, sinh-1, of both sides? sinh-1(ln(x-1)) = sinh-1(sinh(y)) sinh-1(ln(x-1)) = y

    Solving equation with natural log with inverse hyperbolic

    oh sorry, What i meant was "take" not "multiply" even though i typed multiply -_- ok so then, sinh(sinh-1(x)) = sinh-1(sinh(x)) = x ?

    Finding the inverse of function

    so is it: (u - e^-x) / 2 = 0 ? then: u = e^-x ?

    Solving equation with natural log with inverse hyperbolic

    Homework Statement Solve ln(sinh-1(x)) = 1 (Just give the formula for x, no calculator is necessary) sinh-1(x) = asinh Homework Equations The Attempt at a Solution When I did this, I knew sinh-1(x) = ln(x + sqrt.(x^2 +1), but the equation would look like ln(ln(x +...

    Finding the inverse of function

    Homework Statement find the inverse, f(x) = 1 + e^sinh(x) Homework Equations The Attempt at a Solution I am sorry but I never encounter this problem before and my teacher never showed us how to do these kind of problems, I have no idea what to do or how to start it out =[
