Sine, cosine, and tangent functions are super helpful in real life! Here are some places where you might see them:

• Building and Engineering: When people design buildings or bridges, these functions help find heights and angles. For example, if you know how tall a building is and how far away you are from it, you can use the tangent function to find the angle to the top of the building. It looks like this: $\tan(\theta) = \frac{\text{opposite}}{\text{adjacent}}$.

• Science: In science, these functions are important for understanding waves and sounds. The sine function can describe patterns of waves, which means we can use math to understand sound waves or light waves!

• Finding Our Way: When you use GPS to check where you are, sine and cosine help change between different maps. This makes sure you know your exact location.

• Video Games: In gaming and animations, these functions help make movements for characters and objects look real.

Trigonometry plays a big role in the world around us, making it way cooler than it might seem at first!
