Find the derivatives of the functions in Exercises 1–42.

𝔂 = x³ - 3 (x² + π²)

검증된 단계별 안내

Identify the function to differentiate: 𝔂 = x³ - 3(x² + π²).

Apply the power rule to differentiate x³. The power rule states that the derivative of x^n is n*x^(n-1).

Differentiate the term -3(x² + π²). Use the constant multiple rule, which allows you to take the constant outside the derivative, and then apply the power rule to x².

Recognize that π² is a constant, and the derivative of a constant is zero.

Combine the derivatives of each term to find the derivative of the entire function.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Derivative

The derivative of a function measures how the function's output value changes as its input value changes. It is defined as the limit of the average rate of change of the function over an interval as the interval approaches zero. In calculus, 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 and points of tangency.

Power Rule

The power rule is a fundamental technique for finding derivatives of polynomial functions. It states that if f(x) = x^n, where n is a real number, then the derivative f'(x) is given by n*x^(n-1). This rule simplifies the differentiation process, allowing for quick calculations of derivatives for terms involving powers of x.

Constant Rule

The constant rule in differentiation states that the derivative of a constant is zero. This means that if a function includes a constant term, it does not affect the slope of the function at any point. For example, in the function y = x³ - 3(x² + π²), the term -3π² is a constant, and its derivative contributes nothing to the overall derivative of the function.
