The derivative of e^6x provides insights into how the function changes as x changes. Derivatives are useful in various real-life applications, such as determining rates of change and growth. Here, we will delve into the derivative of e^6x in detail.

What is the Derivative of e^6x?

We now explore the derivative of e^6x, which is represented as d/dx (e^6x) or (e^6x)'. The derivative of e^6x is 6e^6x, illustrating that the function is differentiable across its domain.

Key concepts include: -

Exponential Function: e^x is the base function where e is the constant approximately equal to 2.71828. 

Chain Rule: This rule is applied because of the inner function 6x. 

Constant Multiplication: The presence of a constant multiplier in the exponent affects the derivative.

Derivative of e^6x Formula

The derivative of e^6x can be denoted as d/dx (e^6x) or (e^6x)'. To differentiate e^6x, we use the formula: d/dx (e^6x) = 6e^6x This formula applies to all x as the exponential function is defined for all real numbers.

Proofs of the Derivative of e^6x

We can derive the derivative of e^6x using different proofs. To demonstrate, we use differentiation rules such as the chain rule.

Here's how it's done: Using Chain Rule To prove the differentiation of e^6x

using the chain rule: Consider the function f(x) = e^6x. Apply the chain rule, which states that d/dx [f(g(x))] = f'(g(x)) · g'(x).

Here, f(x) = e^x and g(x) = 6x, so: d/dx (e^6x) = e^6x · d/dx (6x) = e^6x · 6 = 6e^6x.

Hence, the derivative of e^6x is 6e^6x, as proved using the chain rule.

Higher-Order Derivatives of e^6x

Higher-order derivatives involve differentiating a function multiple times. They provide insights into the behavior of functions beyond their initial rates of change. For e^6x: -

The first derivative, f'(x), indicates the rate of change of e^6x, which is 6e^6x. 

The second derivative, f''(x), is the derivative of 6e^6x, resulting in 36e^6x. 

Higher-order derivatives follow this pattern, with the nth derivative of e^6x being 6^n e^6x.

Special Cases

There are no undefined points for the derivative of e^6x, as the exponential function is continuous everywhere. However, at x = 0, the derivative is 6e^0, which equals 6.

Common Mistakes and How to Avoid Them in Derivatives of e^6x

Students often make errors when differentiating e^6x. Understanding the correct procedures helps avoid these mistakes. Below are common errors and solutions:

Problem 1

Calculate the derivative of (e^6x · x^3).

Okay, lets begin

Here, we have f(x) = e^6x · x^3. Using the product rule, f'(x) = u'v + uv' In the given equation, u = e^6x and v = x^3.

Let's differentiate each term: u' = d/dx (e^6x) = 6e^6x v' = d/dx (x^3) = 3x^2

Substituting into the product rule, f'(x) = (6e^6x)(x^3) + (e^6x)(3x^2) = 6x^3e^6x + 3x^2e^6x

Thus, the derivative of the specified function is 6x^3e^6x + 3x^2e^6x.

Explanation

We find the derivative of the given function by breaking it into two parts. First, find the derivative of each part and then combine them using the product rule for the final result.

Problem 2

A bank models the growth of an investment with the function V(x) = e^6x, where V represents the value of the investment and x is the time in years. Calculate the rate of growth when x = 2 years.

Okay, lets begin

We have V(x) = e^6x, representing the investment growth. To find the rate of growth, differentiate V(x): dV/dx = 6e^6x.

Substitute x = 2 into the derivative: dV/dx = 6e^(6*2) = 6e^12.

Therefore, the rate of growth of the investment at x = 2 years is 6e^12.

Explanation

We determine the rate of growth by differentiating the function and substituting the given value of x. This provides the instantaneous rate of change of the investment value at x = 2 years.

Problem 3

Derive the second derivative of the function y = e^6x.

Okay, lets begin

First, find the first derivative: dy/dx = 6e^6x.

Now, differentiate the first derivative to find the second derivative: d²y/dx² = d/dx (6e^6x) = 6 · 6e^6x = 36e^6x.

Therefore, the second derivative of the function y = e^6x is 36e^6x.

Explanation

We begin with the first derivative and then differentiate again to find the second derivative. The result shows the second rate of change for the function y = e^6x.

Problem 4

Prove: d/dx (e^12x) = 12e^12x.

Okay, lets begin

Let’s use the chain rule: Consider y = e^12x.

Differentiate using the chain rule: dy/dx = e^12x · d/dx (12x) = e^12x · 12 = 12e^12x.

Hence, proved that d/dx (e^12x) = 12e^12x.

Explanation

In this step-by-step process, we used the chain rule to differentiate the equation, accounting for the constant multiplier in the exponent. The final result confirms the derivative of e^12x.

Well explained 👍

Problem 5

Solve: d/dx (e^6x/x).

Okay, lets begin

To differentiate the function, use the quotient rule: d/dx (e^6x/x) = (d/dx (e^6x) · x - e^6x · d/dx (x))/x²

Substitute d/dx (e^6x) = 6e^6x and d/dx (x) = 1: = (6e^6x · x - e^6x · 1)/x² = (6xe^6x - e^6x)/x² = e^6x(6x - 1)/x².

Therefore, d/dx (e^6x/x) = e^6x(6x - 1)/x².

Explanation

In this process, we differentiate the function using the quotient rule and substitute the derivatives of each part. Finally, simplify the expression for the result.
