___ x - \/ x
x - sqrt(x)
Differentiate −x+x- \sqrt{x} + x−x+x term by term:
Apply the power rule: xxx goes to 111
The derivative of a constant times a function is the constant times the derivative of the function.
Apply the power rule: x\sqrt{x}x goes to 12x\frac{1}{2 \sqrt{x}}2x1
So, the result is: −12x- \frac{1}{2 \sqrt{x}}−2x1
The result is: 1−12x1 - \frac{1}{2 \sqrt{x}}1−2x1
The answer is:
1 1 - ------- ___ 2*\/ x
1 ------ 3/2 4*x
-3 ------ 5/2 8*x
