The t substitution
In various applications of trigonometry, it is useful to rewrite the trigonometric functions (such as sine and cosine) in terms of rational functions of a new variable . These identities are known collectively as the tangent half-angle formulae because of the definition of . These identities can be useful in calculus for converting rational functions in sine and cosine to functions of t in order to fin… WebJul 19, 2005 · It currently doesn't support substitution of the xml with variables.

WebNov 10, 2024 · Figure 7.3.7: Calculating the area of the shaded region requires evaluating an integral with a trigonometric substitution. We can see that the area is A = ∫5 3√x2 − 9dx. To evaluate this definite integral, substitute x = 3secθ and dx = 3secθtanθdθ. We must also change the limits of integration.
