Integrals are an important idea in basic calculus. They help us find the area under curves on a graph.

Think about a graph showing a function. If you want to know how much space is underneath it from one point to another, that’s where integrals come into play!

Key Points:

• Area Under the Curve: An integral helps us calculate the area between the curve and the x-axis (the horizontal line) over a specific range. We write it like this: $\int_a^b f(x) \, dx$

• Accumulation: Integrals also show how things add up, like the total distance you travel over a period of time.

Example:

Let’s say you have a function written as $f(x) = x^2$. If you integrate it from 1 to 3, you can find the area under the curve between those two points. The integral helps you see and calculate that area easily!

In summary, understanding integrals gives us the tools to solve more complicated math problems.
