In basic calculus, you will come across some important symbols. Let’s break them down:

1. Limits: This is shown by the symbol $\lim$. It helps you find out what value a function is getting closer to as the input gets closer to a certain point. For example, you might see something like $\lim_{x \to a} f(x)$.

2. Derivatives: You can see this written as $f'(x)$ or $\frac{dy}{dx}$. This tells us how a function is changing. For example, if we have $f(x) = x^2$, then the derivative $f'(x) = 2x$ tells us how fast it’s changing at any point.

3. Integrals: This is shown by the symbol $\int$. It helps us calculate the area under a curve. For example, $\int f(x) \, dx$ can help us find the total amount of $f(x)$ over a certain range.

These symbols are really important in understanding calculus!
