What is the derivative of a constant value such as 1?

Are you curious to know what is the derivative of 1? You have come to the right place as I am going to tell you everything about the derivative of 1 in a very simple explanation. Without further discussion let’s begin to know what is the derivative of 1?

What is the Derivative of 1?

Calculus, a branch of mathematics developed by luminaries like Isaac Newton and Gottfried Wilhelm Leibniz, is a powerful tool for understanding how things change. One of the fundamental concepts in calculus is the derivative, which measures the rate of change of a function at a particular point. However, you may wonder, what happens when we take the derivative of a constant, such as 1? The answer is both intriguing and essential in understanding the basics of calculus.

Understanding derivatives

Before we delve into why the derivative of 1 is equal to 0, let’s refresh our understanding of derivatives. A derivative measure how a function changes as its input (usually denoted as x) changes. In simple terms, it answers the question: “How fast is a function changing at a specific point?”

Derivative of a constant

Now, let’s consider a constant, like the number 1. When we talk about a constant in calculus, we are essentially discussing a function where the output value remains the same, regardless of changes in the input. In this case, the function can be represented as f(x) = 1 for all values of x.

So, when we take the derivative of the constant function f(x) = 1, we are essentially asking how fast it’s changing at any point. Since the function never changes, the answer is straightforward: the rate of change is zero.

Mathematically, we express this as:

f'(x) = 0

This tells us that the derivative of a constant function is always zero. In other words, no matter where you pick on the graph of the function f(x) = 1, the slope (rate of change) at that point will be zero because the function is perfectly flat.

Why it matters?

Understanding the derivative of a constant is fundamental in calculus and has various practical applications:

Tangent Lines: Derivatives help find the equations of tangent lines to curves. When dealing with horizontal lines (which have a slope of zero), you’re essentially dealing with the derivative of a constant.

Rate of Change: In real-world applications, we often encounter constants that represent unchanging values. Calculating their derivatives helps determine the rate of change or the lack thereof.

Calculus Foundations: Learning the derivative of a constant is a fundamental step in understanding more complex derivatives, such as those of polynomial, trigonometric, and exponential functions.


In calculus, the derivative of a constant, like 1, is always equal to 0. This concept may appear simple, but it forms the foundation for understanding how functions change and how we can calculate rates of change, tangent lines, and more. The derivative of a constant reminds us that, in the world of calculus, some things stay perfectly still, while others are in a constant state of flux.


What is the derivative of negative 1?

The derivative of positive and negative numbers (Constants) is zero, the rate of change or derivative does not change if the number is positive or negative.

What derivatives equal 1?

The derivative of x will be equal to 1. Both the power rule and the first principle can be used to find the derivative of x. By using n =1 in the power given by dxn/dx = nxn-1, the derivative of x can be determined. As f(x) = x represents a straight line, hence, the derivative will be 1 at all points.

Is the derivative of a constant 1?

The derivative (Dx) of a constant (c) is zero. Constant Coefficient Rule: The Dx of a variable with a constant coefficient is equal to the constant times the Dx. The constant can be initially removed from the derivation. Chain Rule: There is nothing new here other than the dx is now something other than 1.

What is the derivative of 2?

Explanation: The derivative is the measure of the rate of change of a function. 2 is a constant whose value never changes. Thus, the derivative of any constant, such as 2, is 0.
