Evaluate Cosh^-1 (0.867)

Answer 1

To evaluate Cosh^-1(0.867), we need to find the inverse hyperbolic cosine of 0.867.

Cosh^-1(x) is the inverse hyperbolic cosine function, which gives the value of angle θ whose hyperbolic cosine is x, i.e., cosh(θ) = x.

Using a calculator, we can find that Cosh^-1(0.867) is approximately equal to 1.222 radians or 70.0 degrees.
