Integral of secx

To find the integral of sec x, we will have to use some facts from trigonometry. We can do the integration of secant x in multiple methods such as:.

In calculus , the integral of the secant function can be evaluated using a variety of methods and there are multiple ways of expressing the antiderivative , all of which can be shown to be equivalent via trigonometric identities ,. This formula is useful for evaluating various trigonometric integrals. In particular, it can be used to evaluate the integral of the secant cubed , which, though seemingly special, comes up rather frequently in applications. The integral of the secant function was historically one of the first integrals of its type ever evaluated, before most of the development of integral calculus. It is important because it is the vertical coordinate of the Mercator projection , used for marine navigation with constant compass bearing. The integral of the secant function was one of the "outstanding open problems of the mid-seventeenth century", solved in by James Gregory. This conjecture became widely known, and in , Isaac Newton was aware of it.

.

There are of course a very large number 1 of trigonometric identities, but usually we use only a handful of them. The most important three are:. Notice that the last two lines of Equation 1. It is also useful to rewrite these last two lines:. These last two are particularly useful since they allow us to rewrite higher powers of sine and cosine in terms of lower powers. For example:. There are many such tricks for integrating powers of trigonometric functions. Here we concentrate on two families. This is typically more laborious than the previous case we studied.

Integral of secx

In this section we look at how to integrate a variety of products of trigonometric functions. These integrals are called trigonometric integrals. They are an important part of the integration technique called trigonometric substitution , which is featured in Trigonometric Substitution. This technique allows us to convert algebraic expressions that we may not be able to integrate into expressions involving trigonometric functions, which we may be able to integrate using the techniques described in this section. In addition, these types of integrals appear frequently when we study polar, cylindrical, and spherical coordinate systems later. For integrals of this type, the identities. After applying these formulas, simplify and reapply strategies 1 through 3 as appropriate. Use strategy 2. These formulas may be derived from the sum-of-angle formulas for sine and cosine.
