Chapter 7, Problem 7.1.14

7–28. Derivatives Evaluate the following derivatives.

d/dx (x^{π})

Verified step by step guidance

Step 1: Recognize that the given function is x raised to the power of π, where π is a constant. The general formula for differentiating x raised to a constant power is d/dx(x^c) = c * x^(c-1), where c is a constant.

Step 2: Identify the constant c in this problem. Here, c = π, which is a mathematical constant approximately equal to 3.14159.

Step 3: Apply the differentiation formula. Substitute c = π into the formula, resulting in d/dx(x^π) = π * x^(π-1).

Step 4: Simplify the expression. The derivative is now expressed as π * x^(π-1).

Step 5: Conclude that the derivative has been successfully computed symbolically. No further simplification is needed unless numerical evaluation is required.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Derivatives

A derivative represents the rate of change of a function with respect to a variable. It is a fundamental concept in calculus that measures how a function's output value changes as its input value changes. The derivative is often denoted as f'(x) or dy/dx, and it provides critical information about the function's behavior, such as its slope at any given point.

Power Rule

The Power Rule is a basic differentiation rule used to find the derivative of functions in the form of x^n, where n is a real number. According to this rule, the derivative of x^n is n*x^(n-1). This rule simplifies the process of differentiation for polynomial and power functions, making it easier to compute derivatives quickly.

Constant Exponents

In calculus, when dealing with functions that have constant exponents, such as x raised to π (a constant), the Power Rule still applies. The exponent π is treated as a constant, allowing us to differentiate the function using the same principles as with integer exponents. This concept is crucial for understanding how to handle derivatives of functions involving irrational or non-integer exponents.
