1 / | | cos(x) | ------------- dx | 5 + 10*sin(x) | / 0
Integral(cos(x)/(5 + 10*sin(x)), (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 is .
So, the result is:
Now substitute back in:
Add the constant of integration:
The answer is:
/ | | cos(x) log(5 + 10*sin(x)) | ------------- dx = C + ------------------ | 5 + 10*sin(x) 10 | /
log(2) log(1/2 + sin(1)) ------ + ----------------- 10 10
=
log(2) log(1/2 + sin(1)) ------ + ----------------- 10 10
log(2)/10 + log(1/2 + sin(1))/10
Use the examples entering the upper and lower limits of integration.
