Trigonometric Substitution
- Trigonometric functions can be substituted for other expressions to change the form of integrands and simplify the integration.
- Trigonometric functions can be substituted for other expressions to change the form of integrands.
- One may use the trigonometric identities to simplify certain integrals containing radical expressions (or expressions containing $n$th roots).
- The following are general methods of trigonometric substitution, depending on the form of the function to be integrated.
-
Trigonometric Integrals
- The trigonometric integrals are a specific set of functions used to simplify complex mathematical expressions in order to evaluate them.
- The trigonometric integrals are a family of integrals which involve trigonometric functions ($\sin$, $\cos$, $\tan$, $\csc$, $\cot$, $\sec$).
- The following is a list of integrals of trigonometric functions.
- Some of them were computed using properties of the trigonometric functions, while others used techniques such as integration by parts.
- Generally, if the function, $\sin(x)$, is any trigonometric function, and $\cos(x)$ is its derivative, then

Using Calculators and Computers
- Scientific calculators are used widely in any situation where quick access to certain mathematical functions is needed, especially those such as trigonometric functions that were once traditionally looked up in tables; they are also used in situations requiring back-of-the-envelope calculations of very large numbers, as in some aspects of astronomy, physics, and chemistry.
