Integral of sin(cos(x))

Hi. I was trying to find the integral of sin(cos(x)) using matlab but it gives me this message 'Explicit integral could not be found'. Can anybody help me how to find this integral?

syntax:

syms x
int(sin(cos(x)), x)

It is very simple dear friend, there is no primitive for that integral, instead you can use development in series of taylor or numerical integration methods

Answer 1

[Kye Taylor]

Ultimately, are you trying to compute a definite integral? If there are limits, you may be able to use Bessel functions to evaluate it. Check out http://en.wikipedia.org/wiki/Bessel_function#Bessel.27s_integrals Or, if the limits of the intergral are functions themselves, there may still be hope with an integral transform.

Answer 2

[Walter Roberson]

There is no analytic integral for that.
