Hyperbolic functions, which are defined using the hyperbola rather than the circle, are comparable to normal trigonometric functions. Hyperbolic functions are used in hyperbolic geometry to compute angles and distances. They also show up in the solutions to a large number of linear differential equations, cubic equations, etc. For given angle$\theta$. The hyperbolic cosine function cosh$(\theta)$ is like below $$\mathrm{cos(x)\:=\:\frac{e^x\:+\:e^{-x}}{2}\:=\:\frac{e^{2x}+1}{2e^x}\:=\:\frac{1+e^{-2x}}{2e^{-x}}}$$ In this article, we shall discuss the techniques to get the value of cosh$(\theta)$ in C++ when the angle is given in the radian unit.

Multiplying the same number thrice is termed as the cube of that number. Or we can say the number raised to power 3. For instance 3 * 3 * 3 = 27, which is a cubic number. But if we want to perform the reverse operation, we need to find the cube root of the number. For example $\sqrt[3]{27}$ = 3. In this article, we shall discuss how to calculate the cube root of a given number in C++. There are a few different techniques to do so.
