"Because the derivative of a function $y=f(x)$ is itself a function $y'=f'(x)$, you can take the derivative of $f'(x)$, which is generally referred to as the second ...

Remember that integration is the inverse procedure to differentiation. So, if you can do trigonometric differentiation, you can do trig integration.

Differentiation Differentiating simple trigonometric expressions Differentiation of algebraic and trigonometric expressions can be used for calculating rates of change, stationary points and their ...

We investigate the hydrodynamic behaviour of zeroes of trigonometric polynomials under repeated differentiation. We show that if the zeroes of a real-rooted, degree d trigonometric polynomial are ...
