Integral(pi*(6/x)^2, (x, 1, 4))
The integral of a constant times a function is the constant times the integral of the function:
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 a constant is the constant times the variable of integration:
So, the result is:
Now substitute back in:
So, the result is:
Add the constant of integration:
The answer is:
/ | | 2 | /6\ 36*pi | pi*|-| dx = C - ----- | \x/ x | /
