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:, integral of secx. We have multiple formulas for integration of sec x and let us derive each of them using the above mentioned methods. Also, we will solve some examples related integral of secx the integral of sec x.

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.

.

This is also known as the antiderivative of sec x. Applying this. Bernoulli numbers e mathematical constant Exponential function Natural logarithm Stirling's approximation.

.

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.

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.

It is also possible to find the other two hyperbolic forms directly, by again multiplying and dividing by a convenient term:. Integral of Sec x To find the integral of sec x, we will have to use some facts from trigonometry. Now, we have. But why do we need to do this? Article Talk. Specialized Fractional Malliavin Stochastic Variations. This formula is useful for evaluating various trigonometric integrals. A similar strategy can be used to integrate the cosecant , hyperbolic secant , and hyperbolic cosecant functions. Because the constant of integration can be anything, the additional constant term can be absorbed into it. Bernoulli numbers e mathematical constant Exponential function Natural logarithm Stirling's approximation. Exercitationes Geometricae [ Geometrical Exercises ] in Latin. It is important because it is the vertical coordinate of the Mercator projection , used for marine navigation with constant compass bearing.

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:.

Conformal Projections Based on Elliptic Functions. Integral of Sec x by Hyperbolic Functions. This was the formula discovered by James Gregory. Cengage Learning. This substitution can be obtained from the derivatives of secant and tangent added together, which have secant as a common factor. United Kingdom. Commercial Maths. Maths Formulas. Math worksheets and visual curriculum. We have multiple formulas for this.
