First make a substitution and then use integration by parts to evaluate the integral sin(sqrt(x)) dx. There are numerous integrals containing this exponential function in both explicit and implicit form. Let us derive some of these.sin( x. x)]exp(. x)dx. 1 i. from which follows that Tutorial to find integrals involving the product of sin(x) or cos(x) with exponential functions. Exercises with answers are at the bottom of the page.Let u sin(x) and dv/dx ex and then use the integration by parts as follows. sin(x)ex dx sin(x)ex - cos(x)ex dx. I applied this to int(xsin(x),x) for example and got my answer but, couldnt use for int( exp(x)sin(x),x) . I ask if this rule command packaged under with(student) can be applied for a certain kinds of integral or not?exp(x) sin(x) dx - exp(x) sin(x) - - cos(x) exp(x) |. ex sin x dx -ex cos x - -ex cos x dx. If you substitute the values of u, v, du/ dx into the standard formula for integration by parts then you get the above expression. However, as you can see you are left with another puzzle on the RHS which is ex cos x dx. Start studying Таблица интегралов.
