## What does the derivative mean in a word problem?

the rate of change
The derivative is the rate of change (or slope) at a particular point. It is saying, as I change the input the output changes by however much.

What are the 4 derivative Rules?

Power Rule: If xn is the function, then the derivative is nxn-1. Quotient Rule: If the function is f/g, then the derivative is [f’g-g’f]/g2. Reciprocal Rule: If the function is 1/f, then the derivative is -f’/f2. Chain Rule: If f⚬g is the function, then the derivative of the function is (f’ ⚬ g) x g’.

### What are the 5 derivative Rules?

Rules of Differentiation of Functions in Calculus

• 1 – Derivative of a constant function.
• 2 – Derivative of a power function (power rule).
• 3 – Derivative of a function multiplied by a constant.
• 4 – Derivative of the sum of functions (sum rule).
• 5 – Derivative of the difference of functions.

What is a derivative example?

What Are Some Examples of Derivatives? Common examples of derivatives include futures contracts, options contracts, and credit default swaps. Beyond these, there is a vast quantity of derivative contracts tailored to meet the needs of a diverse range of counterparties.

What does a derivative tell you?

Just like a slope tells us the direction a line is going, a derivative value tells us the direction a curve is going at a particular spot. At each point on the graph, the derivative value is the slope of the tangent line at that point.

### Why is derivative used?

Derivatives are used to find the rate of changes of a quantity with respect to the other quantity. The equation of tangent and normal line to a curve of a function can be calculated by using the derivatives. Derivative of a function can be used to find the linear approximation of a function at a given value.

What is a derivative easy explanation?

The derivative is the instantaneous rate of change of a function with respect to one of its variables. This is equivalent to finding the slope of the tangent line to the function at a point.

## What is the derivative of ln3?

Since ln(3) is constant with respect to x , the derivative of ln(3) with respect to x is 0 .
