To find the second derivative of ( f(x) = x^2 \ln(x) ), first, compute the first derivative of ( f(x) ), then differentiate the result again with respect to ( x ).

First derivative: [ f'(x) = 2x \ln(x) + \frac{x^2}{x} = 2x \ln(x) + x ]

Second derivative: [ f''(x) = \frac{d}{dx}(2x \ln(x) + x) = 2 \ln(x) + 2 + 1 = 2 \ln(x) + 3 ]

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- How do you determine whether the function #f(x)= sinx-cosx# is concave up or concave down and its intervals?
- How do you find the x coordinates of all points of inflection, final all discontinuities, and find the open intervals of concavity for #y=2x^2+4x+4#?
- If # f(x) = ( x^3 )/( x^2 - 25 )#, what are the points of inflection, concavity and critical points?
- Is #f(x)=xlnx-x# concave or convex at #x=1#?
- What are the points of inflection, if any, of #f(x) =12x^5+15x^4–240x^3+6#?
