x INTEGRAL RULES. ∫ sin xdx = − cos x + c. ∫ cos xdx = sin x + c. ∫ sec 2 xdx = tan x + c.
The Rule: . arctan. OR . arctan. Putting everything together: . Use this rule when you have a fraction of the form: where the polynomial in the denominator does . not factor and the fraction is not in the correct form to turn into an . Example: evaluate . From the example above we know that .
Integrals of Trigonometric Functions. ∫ sin x dx = − cos x + C. ∫ cos x dx = sin x + C. ∫ tan x dx = ln sec x + C. ∫ sec x dx = ln tan x + sec x + C. ∫ 1. sin. 2. x dx = ( x − sin x cos x ) + C.

7.3 CALCULUS WITH THE INVERSE TRIGONOMETRIC FUNCTIONS. The three previous sections introduced the ideas of one–to–one functions and inverse functions and used. those ideas to define arcsine, arctangent, and the other inverse trigonometric functions. Section 7.3 presents. the calculus of inverse trigonometric functions.
