Basic Integration Formulas for Calculus 1

## TL;DR

This video explains three basic integration rules: the formula for integrating zero, the formula for integrating a constant, and the power rule.

## Key Insights

• 🫡 The integral of zero with respect to X is the constant function.
• ✖️ Integrating a constant with respect to X results in the constant multiplied by X, plus a constant of integration.
• ✊ The power rule is a fundamental rule for integration, allowing us to integrate functions of the form X to the power of n.
• 🍉 The sum rule enables us to integrate functions by integrating each term separately.
• ❓ Integration is the process of finding the antiderivative of a function.
• ❓ The constant of integration can take any value and represents the many possible solutions to an indefinite integral.
• ✊ The power rule is only valid for exponents that are not equal to -1.

## Transcript

hi everyone in this video we're going to discuss some of the basic integration rules so the first rule we're going to look at is a formula for the integral of zero with respect to X so when we're trying to integrate zero with respect to X we have to ask ourselves what is a function whose derivative is zero right because we're going backwards well t...

### Q: What is the formula for integrating zero with respect to X?

The formula states that the integral of zero with respect to X is the constant function. This is because the derivative of a constant function is zero, and integrating zero should bring us back to the constant function.

### Q: How do we integrate a constant with respect to X?

To integrate a constant, denoted as K, with respect to X, we simply multiply the constant by X and add a constant of integration. This is because the derivative of KX is K, and the derivative of a constant is zero.

### Q: What is the power rule for integration?

The power rule states that when integrating X to the power of n with respect to X, we add 1 to the exponent, divide by the new exponent, and add a constant of integration. This formula is valid as long as the exponent is not equal to -1.

### Q: How do we integrate the function 2x + 3 with respect to X?

We can integrate each term separately using the sum rule. For the term 2x, we apply the power rule to get (2/2)x^2 = x^2, and for the term 3, we simply multiply by X to get 3x. The result is x^2 + 3x + C, where C is the constant of integration.

## Summary & Key Takeaways

• The first integration rule states that when integrating zero with respect to X, the result is the constant function.

• The second integration rule states that when integrating a constant with respect to X, the result is the constant multiplied by X, plus a constant of integration.

• The third integration rule, known as the power rule, states that when integrating X to the power of n with respect to X, the result is X to the power of n+1 divided by n+1, plus a constant of integration.
