y = (x3√(x2 + 1))/(x - 1)
What I did:
I used natural log on both sides.
I brought the exponents into the coefficient.
I also brought the (x - 1) up by doing it to the negative one exponent
Then I used the log properties.
So tell me if this is the correct way:
ln y = 3lnx + (1/2)ln(x2 + 1) - ln(x - 1)
Then I find the derivative
1/y(dy/dx) = 3/x + (1/2)(1/(x2 + 1)) - (1/(x - 1))
After that I multiplied both sides by y, then plugged in y, which is the original equation.
So would this be right?
