1 / | | sin(y)*cos(y) dy | / 0
Integral(sin(y)*cos(y), (y, 0, 1))
There are multiple ways to do this integral.
Let .
Then let and substitute :
The integral of is when :
Now substitute back in:
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:
Add the constant of integration:
The answer is:
/ 2 | sin (y) | sin(y)*cos(y) dy = C + ------- | 2 /
2 sin (1) ------- 2
=
2 sin (1) ------- 2
