    Could i get some help working out dy/dx of arccoth(x)

    does that mean 1 = -1/sinh^2(y) * (coth(y))

    Could i get some help working out dy/dx of arccoth(x)

    Homework Statement y=arccoth(x), find the derivative Homework Equations cothx - coshx/sinhx The Attempt at a Solution y = arccoth(x) x = coth(y) = cosh(y)/sinh(y) quotient rule = (sinh(y)*sinh(y))-(cosh(y)*cosh(y))/(sinh(y))^2 = sinh^2(y) - cosh^2(y)/sinh^2(y) x=...
