Power rule of an integration [beginner]

In summary, the power rule of integration is a mathematical rule used to integrate functions with a variable raised to a power. It involves increasing the power of the variable by 1 and dividing the entire function by the new power. It cannot be used for functions with trigonometric, logarithmic, or exponential terms. The power rule of integration is different from the power rule of differentiation, as it is used to find the antiderivative of a function instead of its derivative. It can also be combined with other integration rules and techniques, such as substitution and integration by parts.

So I stumbled upon ∫1/(x^4) , and by applying the power rule , the answer is: -1/(3x^3)

Why's that? Sorry for bothering you guys with such a beginner question!

Write the fraction as x^-4, and apply the power rule and you will quickly see why that is the answer!

What is the power rule of integration?

The power rule of integration is a mathematical rule used to integrate functions with a variable raised to a power. It states that when integrating a function, the power of the variable is increased by 1 and then divided by the new power.

How do you apply the power rule of integration?

To apply the power rule of integration, you first increase the power of the variable by 1. Then, you divide the entire function by the new power. If the power is negative, you can rewrite the function as 1 over the variable raised to the positive power and then apply the power rule.

Can the power rule of integration be used for all functions?

No, the power rule of integration can only be used for functions with a variable raised to a power. It cannot be used for functions with trigonometric, logarithmic, or exponential terms.

What is the difference between the power rule of integration and the power rule of differentiation?

The power rule of integration is used to find the antiderivative of a function, while the power rule of differentiation is used to find the derivative of a function. The power rule of differentiation involves subtracting 1 from the power of the variable, while the power rule of integration involves adding 1 and dividing by the new power.

Can the power rule of integration be combined with other integration rules?

Yes, the power rule of integration can be combined with other integration rules, such as the constant multiple rule or the sum rule. It can also be used in conjunction with substitution, integration by parts, and other advanced integration techniques.
