Introduction to the Derivative of e^2x
Derivatives have a wide range of applications in almost every field of engineering and science. The derivative of e can be calculated by following the rules of differentiation. Or, we can directly find the derivative of e^2 by applying the first principle of differentiation. In this article, you will learn what the derivative of e2x is and how to calculate the derivative of e2x by using different approaches.
What is the derivative of e^2x?
The derivative of e^2x is equal to 2e^2x. This can be represented as d/dx (e^2x). Essentially, the derivative of e^x measures the rate of change of the function; in this case, it is always equal to the negative of the original function. Understanding the e2x differentiation is important in various fields of mathematics and sciences, such as calculus and physics.
Derivative of e2x formula
The formula for the differentiation of e^(2x) is equal to the 2 multiplied by e^(2x). Mathematically,
d/dx (e^2x) = e^2x
It is important to note that the e^2x differentiation is not the same as the derivative of e^(-2x), which is equal to -2e^(2x).
How do you prove the derivative of e2x?
There are multiple rules of differentiation for finding the derivative of e^(2x). The most common ways are;
- First Principle
- Product Rule
- Quotient Rule
Each method provides a different way to compute the e^2x derivative. By using these methods, we can mathematically prove the formula for finding the derivative of e^(2x).
Derivative of e2x by first principle
According to the first principle of derivative, the ln e^(2x) derivative is equal to 2e^(2x). The derivative of a function by the first principle refers to finding a general expression for the slope of a curve by using algebra. It is also known as the delta method. The derivative is a measure of the instantaneous rate of change, which is equal to,
f(x)=lim f(x+h)-f(x) / h
This formula allows us to determine the rate of change of a function at a specific point by using the limit definition of the derivative.
Proof of e2x differentiation by first principle
To differentiate e^2x by using first principle, we start by replacing f(x) by e^(2x). You can also replace f(x) by e^8x to calculate the derivative of e^8x.
f'(x)=limh→0f(x+h)-f(x)/h
f'(x) = lim e^2(x+h) - e^2x/h
Moreover,
f'(x) = lim e^2x.e^2h - e^2x/h
Taking e^2x common as;
f'(x) = lim e^2x(e^2h - 1)/h
More simplification,
f'(x) = e^2x .lim (e^2h - 1)/-h
When h approaches to zero,
f'(x) = 2e^2x lim (e0- 1)/2h
f'(x) = 2e^2x f(0)
Therefore,
f'(x) = 2e^2x
Hence the derivative of e^2x can also be calculated by using derivative by definition calculator.
Derivative of e^2x by product rule
Another method to find the derivative e^(2x) is the product rule formula which is used in calculus to calculate the derivative of the product of two functions. Specifically, the product rule is used when you need to differentiate two functions that are multiplied together. The formula for the product rule calculator is:
d/dx(uv) = u(dv/dx) + (du/dx)v
In this formula, u and v are functions of x, and du/dx and dv/dx are their respective derivatives with respect to x.
Proof of e^2x differentiation by product rule
To prove the derivative e^2x by using the product rule, we start by assuming that,
f(x) = 1. e^2x
By using product rule of differentiation,
f'(x) = (e^2x). 1 + (1)e^2x
We get,
f'(x) = 2e^2x + 0
Hence,
f'(x) = 2e^2x
Derivative of e^2x using quotient rule
Since the exponential function can be written as the reciprocal of e^(2x). Therefore, the derivative of e^2x can also be calculated by using the quotient rule. The quotient rule is defined as;
d/dx (f/g) = f(x). g(x) -g(x).f(x) /{g(x)}2
Proof of derivative of e^2x by quotient rule
To prove the derivative of e^2x, we can start by writing it,
f(x) = e^2x /1 = u/v
Supposing that u = e^2x and v = 1. Now by quotient rule calculator,
f'(x) = (vu - uv)/v2
f'(x) = [d/dx(e^2x) - e^2x .d/dx(1)] / (1)2
= [2e^2x] / 1
= 2e^2x
Hence, we have derived the differential of e^2x using the quotient rule of differentiation calculator.
