Trig substitution calculator
Techniques of Integration. By changing variables, integration can be simplified by using the substitutions x=a\sin (\theta), x=a\tan (\theta), or x=a\sec (\theta). Once the substitution is made the function can be simplified using basic trigonometric identities.Trig Substitution Cheat Sheet. This substitution allows one to evaluate integrals that would otherwise difficult or impossible to solve. Here a cheat sheet of the most common trigonometry substitution formulas: √ (a^2 – x^2) = sinθ. Where a is a constant, x is the variable being integrated, and θ is the angle whose sine is equal to x/a.
