1 / | | 2 / 3\ | x *sin\x /*1 dx | / 0
Integral(x^2*sin(x^3)*1, (x, 0, 1))
Let .
Then let and substitute :
The integral of a constant times a function is the constant times the integral of the function:
The integral of sine is negative cosine:
So, the result is:
Now substitute back in:
Add the constant of integration:
The answer is:
/ | / 3\ | 2 / 3\ cos\x / | x *sin\x /*1 dx = C - ------- | 3 /
1 cos(1) - - ------ 3 3
=
1 cos(1) - - ------ 3 3
Use the examples entering the upper and lower limits of integration.
