1 / | | x | ------------ dx | 2 | _________ | \/ 5 - 2*x | / 0
Integral(x/(sqrt(5 - 2*x))^2, (x, 0, 1))
Rewrite the integrand:
The integral of a constant times a function is the constant times the integral of the function:
Rewrite the integrand:
Integrate term-by-term:
The integral of a constant is the constant times the variable of integration:
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 is .
So, the result is:
Now substitute back in:
So, the result is:
The result is:
So, the result is:
Add the constant of integration:
The answer is:
/ | | x 5*log(-5 + 2*x) x | ------------ dx = C - --------------- - - | 2 4 2 | _________ | \/ 5 - 2*x | /
1 5*log(3) 5*log(5) - - - -------- + -------- 2 4 4
=
1 5*log(3) 5*log(5) - - - -------- + -------- 2 4 4
-1/2 - 5*log(3)/4 + 5*log(5)/4
