Question

find the derivative of /[/3 sqrt{x- frac{1/x}}/]/? pls hlp

Answer 1

\[3*\sqrt{\frac{x-1}{x}}\]???

Answer 2

To do fractions, type "frac{numerator}{denominator}"

Answer 3

\[find the derivative of 3\sqrt{x-1/x}\]

Answer 4

Factor out constants and use the chain rule and you get
\[(3 (1+1/x^2))/(2 \sqrt(-1/x+x))\]

Answer 5

how?

Answer 6

Natalie, I think you're making it a little more complicated than it needs to be.
Just use chain rule:
Derivative of\[3\sqrt(x)\]?

Answer 7

That's the outside function. The inside function is x-(1/x).
Chain rule says:
do derivative of the ouside function. Multiply by the derivative of the inside function.

Answer 8

\[3 d/dxsqrt{x}= 3/2sqrt{x}\]\

Answer 9

\[d/dx \sqrt{1/x}=\]

Answer 10

ok so the answer s\[3/2\sqrt{x}+1/x^{2}\]

Answer 11

is this correct?
