WebIn a right angled triangle, the secant of an angle is: The length of the hypotenuse divided by the length of the adjacent side. The abbreviation is sec sec (θ) = hypotenuse / adjacent It is not commonly used, and is equal to 1/cosine Sine, Cosine, Tangent WebRecall that if $$ x = f(\theta) \ , $$ $$ dx = f'(\theta) \ d\theta $$ For example, if $$ x = \sec \theta \ , $$ then $$ dx = \sec \theta \tan \theta \ d\theta $$ The goal of trig substitution will be to replace square roots of quadratic expressions or rational powers of the form $ \ \displaystyle \frac{n}{2} \ $ (where $ \ n \ $ is an integer) of quadratic expressions, which … WebThis problem has been solved!
