Derivative-free optimisation techniques have emerged as indispensable tools in addressing complex problems where gradient information is either unavailable or unreliable. Such methods bypass the need ...

The trigonometric interpolants to a periodic function f in equispaced points converge if f is Dini-continuous, and the associated quadrature formula, the trapezoidal rule, converges if f is continuous ...

Mastering degree-radian conversions is crucial for trigonometry and calculus. Radians simplify mathematical formulas, especially in calculus where trigonometric function derivatives rely on radian ...
