pi -- 2 / | | sin(x) | 12 *cos(x) dx | / 0
Integral(12^sin(x)*cos(x), (x, 0, pi/2))
Let .
Then let and substitute :
The integral of an exponential function is itself divided by the natural logarithm of the base.
Now substitute back in:
Add the constant of integration:
The answer is:
/ | sin(x) | sin(x) 12 | 12 *cos(x) dx = C + -------- | log(12) /
11 ------- log(12)
=
11 ------- log(12)
11/log(12)
Use the examples entering the upper and lower limits of integration.
