Integral(E^3*sin(x)*cos(x), (x, 0, 1))
The integral of a constant times a function is the constant times the integral of the function:
There are multiple ways to do this integral.
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 is when :
So, the result is:
Now substitute back in:
Let .
Then let and substitute :
The integral of is when :
Now substitute back in:
So, the result is:
Add the constant of integration:
The answer is:
/ | 2 3 | 3 cos (x)*e | e *sin(x)*cos(x) dx = C - ---------- | 2 /
2 3 sin (1)*e ---------- 2
=
2 3 sin (1)*e ---------- 2
