The tangent graph is different from the sine and cosine graphs in a few important ways. Let's break down these differences into simple pieces.

1. Periodicity:

Sine and cosine functions repeat their patterns every $2\pi$ radians.

But the tangent function has a shorter cycle. It repeats every $\pi$ radians.

This means the tangent graph shows its full pattern twice as quickly compared to sine and cosine.

If you were to look at the tangent graph, you would notice its pattern repeated every $\pi$ radians.

2. Asymptotes:

One big thing that makes the tangent graph stand out is its vertical asymptotes.

But what are asymptotes?

They are lines where the graph goes off to infinity.

For the tangent function, it’s defined by the formula: $\tan(x) = \frac{\sin(x)}{\cos(x)}$.

When the cosine equals zero, the tangent shoots up to infinity, creating those vertical lines.

These lines happen at special points called odd multiples of $\frac{\pi}{2}$, like $x = \frac{\pi}{2} + k\pi$ where $k$ can be any whole number.

In comparison, sine and cosine don’t have these vertical lines, which makes their graphs look smoother and more continuous.

3. Range and Values:

Now, let’s talk about the range of these functions.

The range of the tangent function includes all real numbers.

This means tangent can be any number from negative to positive infinity, like $(-\infty, \infty)$.

On the other hand, sine and cosine have a limited range, only going from $-1$ to $1$.

This difference helps explain why tangent behaves the way it does with those vertical lines.

Illustration Example:

To help you picture it, imagine drawing the sine, cosine, and tangent functions on the same graph.

The sine wave smoothly goes up and down between -1 and 1.

The cosine graph looks like a mirrored version of the sine graph.

But the tangent graph? It shoots up to infinity as it gets close to each vertical line, making steep “humps.”

In conclusion, the tangent graph is special because it has a shorter cycle of $\pi$, vertical lines that shoot to infinity, and can show any number instead of just staying between -1 and 1.

These features make tangent an interesting topic when studying trigonometric graphs!
