Differentiation of **trigonometric** functions - Wikipedia

en.wikipedia.org/wiki/Differentiation_of_trigonometric_functions
The differentiation of ** trigonometric functions** is the mathematical process of finding the derivative of a

**function, or its rate of change with respect to a variable.For example, the derivative of the sine function is written sin′(a) = cos(a), meaning that the rate of change of sin(x) at a particular angle x = a is given by the cosine of that angle.**

** Trigonometric identities** like sin²θ+cos²θ=1 can be used to rewrite expressions in a different, more convenient way. For example, (1-sin²θ)(cos²θ) can be rewritten as (cos²θ)(cos²θ),

**and**then as cos⁴θ.
