When evaluating a trigonometric substitution, one follows a systematic process for simplifying integrals involving radical expressions. The selection of the appropriate substitution, such as x=asin(θ) or x=atan(θ), hinges on the structure of the integral. Once the substitution is applied, the expression transforms into a trigonometric form, making the integration more manageable. Adjustments to the limits are crucial to reflect the new variable. Subsequently, the integration is in terms of the trigonometric variable, and the result is then back into the original variable.
This method is particularly effective when dealing with square roots or other radical terms in integrals. While specific steps may vary depending on the integral, the careful application of trigonometric substitutions and careful algebraic manipulations ensures a precise and efficient evaluation of integrals within calculus.

In trigonometry, tangent and cotangent functions are undefined at angles where the cosine is zero, as division by zero is undefined. Therefore, tan (90°) and cot (0°) are undefined. Additionally, secant is undefined at angles where the cosine is zero, and cosecant is undefined where the sine is zero. Understanding these undefined points is crucial for avoiding mathematical inconsistencies in trigonometric calculations.
Trigonometric functions, such as sine, cosine, tangent, and their derivatives, are not polynomials. Unlike polynomials, trigonometric functions involve ratios of sides in right-angled triangles or points on the unit circle. The periodic nature of trigonometric functions makes them suitable for modeling oscillatory phenomena in various fields, such as physics.
Use u-substitution when dealing with integrals where a simple substitution of variables can simplify the expression, often involving algebraic or exponential functions. Trig substitution is more suitable when confronted with integrals containing radicals or when u-substitution alone is insufficient. Trig substitution involves substituting trigonometric functions to simplify and solve the integral. The choice between u-substitution and trig substitution depends on the structure of the integral and the most effective approach for simplifying the expression.
The purpose of using a trigonometric substitution is to simplify and solve integrals that involve radical expressions. The integral can be converted into a more manageable form by substituting trigonometric functions such as sine, cosine, or tangent. Trigonometric substitution is particularly effective in handling square roots or expressions involving the Pythagorean identity. This technique enables the integration of complex expressions in calculus, providing a powerful tool for evaluating a diverse range of integrals.
