Here are useful rules to help you work out the derivatives of many functions (with examples below). Use n√ax = ax n a x n = a x n to rewrite √x x as x1 2 x 1 2. d dx [x1 2] d d x [ x 1 2] Differentiate using the Power Rule which states that d dx [xn] d d x [ x n] is nxn−1 n x n - … The resulting number 9 is called the square of a square root. Square of Fraction is one of the basic mathematic functions used to find the squared value of either positive or negative fraction number expressed by both non-zero numerator and denominator, by multiplying the fraction itself twice. Now use the multiplication rule: Put u = x 3 gives u´ = 3x 2 and v = x 2 gives v´ = 2x. The Derivative tells us the slope of a function at any point.. The sign/abbreviation for square root is sqrt. This looked too messy. I'm having a problem getting my textbook's answer for this question. The square root of a fraction is the square root of the top divided by the square root of the bottom. Find the derivative: \begin{equation*} h(x) = \frac{\sqrt{\ln x}}{x} \end{equation*} This is a problem where you have to use the chain rule. Using the definition of the derivative with a function involving a fraction and square root. Remember that a square root is a number multiplied by it to get the resulting number.
