Emma Jonson What is the alternative formula?
For a population, the variance is calculated as σ² = ( Σ (x-μ)² ) / N. Another equivalent formula is σ² = ( (Σ x²) / N ) – μ². If we need to calculate variance by hand, this alternate formula is easier to work with.
How do you find the formula for the derivative of a function?
Basically, we can compute the derivative of f(x) using the limit definition of derivatives with the following steps:
- Find f(x + h).
- Plug f(x + h), f(x), and h into the limit definition of a derivative.
- Simplify the difference quotient.
- Take the limit, as h approaches 0, of the simplified difference quotient.

How do you find the derivative of a derivative?
To find the derivative of a function y = f(x) we use the slope formula: Slope = Change in Y Change in X = ΔyΔx. And (from the diagram) we see that: Now follow these steps: Fill in this slope formula: ΔyΔx = f(x+Δx) − f(x)Δx. Simplify it as best we can. Then make Δx shrink towards zero.
What are the rules of differentiation?
The Basic Differentiation Rules. Some differentiation rules are a snap to remember and use. These include the constant rule, power rule, constant multiple rule, sum rule, and difference rule. The constant rule: This is simple. f ( x) = 5 is a horizontal line with a slope of zero, and thus its derivative is also zero.
What is the formula for differentiation?
Differentiation Formulas. Some of the important Differentiation formulas in differentiation are as follows. If f(x) = tan (x), then f'(x) = sec 2x. If f(x) = cos (x), then f'(x) = -sin x. If f(x) = sin (x), then f'(x) = cos x.
What is the limit definition of derivative?
Definition of derivative of a function. : the limit if it exists of the quotient of an increment of a dependent variable to the corresponding increment of an associated independent variable as the latter increment tends to zero without being zero.
