How do you find the derivative of #(2sqrtx - 1)/(2sqrtx)#?
We could use the quotient rule, stating that:
It is however easier to write the function as:
Break it into two fractions, the first becomes the derivative of a constant, and the second can be differentiated as a negative power.
Break into two fractions:
The derivative of a constant is zero and use the power rule on the second term:
