Substitution won't help much here. This is not integrable in the elementary functions. Ignoring the first part, which is easy, the result is a constant times the difference between an elliptical integral of the first kind and an elliptical integral of the second kind.mfb said:Do you know substitution?
sin(x)=u is a possible approach, and that method might work as well.

The *denominator* is a square root. The *numerator* is -sin(x)2.yanic said:Hi,
The numerator is a square root. I can't see how rewriting the numerator in such a way
will lead me to the expected result.
Please can you give further indications?

Did you read my first post? You can try all the substitutions you want and you will *never* be able to find an analytic solution to this problem in the elementary functions. This problem is not integrable in the elementary functions. Fortunately, there are two special functions that are very applicable to this problem, the elliptical integrals of the first and second kind. The standard definitions of these functions areyanic said:Sorry
Yeah I see. I have tried but that won't help either.
DId you get any result with that substitution?
The problem is the last term of the integration by part
that always contains at the denominator √([sin]^{2}(x)+c)
An integral is a mathematical concept that represents the accumulation of a quantity over a given interval. It is often used to find the area under a curve in a graph or to calculate the total amount of a changing quantity.
To solve an integral, you need to use integration techniques such as substitution, integration by parts, or partial fractions. You also need to have a good understanding of the fundamental theorem of calculus and the properties of integrals.
A definite integral has specific limits of integration, meaning it is evaluated over a specific interval. On the other hand, an indefinite integral has no limits of integration and represents a general solution to the integral.
Integrals have many practical applications in fields such as physics, engineering, economics, and statistics. They are used to calculate areas, volumes, work, and other quantities that are continuously changing.
No, not all functions can be integrated. Some functions are non-integrable, meaning they do not have an antiderivative. In these cases, numerical methods or approximations can be used to find an approximate solution to the integral.
