Detailed Description

template<typename Scalar>
requires TypeTrait<Scalar>::IsScalar
class Optimist::TestSet::Sinh< Scalar >

Class container for the hyperbolic sine function, which is defined as:

\[f(x) = \sinh(x) = \displaystyle\frac{e^x - e^{-x}}{2} \text{.} \]

The function has a zero at \(x = 0\), with \(f(x) = 0\). The initial guesses are generated on the range \(x \in \left[-10, 10\right]\).

Template Parameters

Scalar

Floating-point number type.
