Sine, cosine, and tangent are super important in Year 12 Maths. They help us see how angles and sides of triangles connect. Let’s break down why they are so useful:

1. Basic Definitions:

   • Sine ($\sin$): This is the comparison of the side opposite the angle to the longest side (hypotenuse) in a right triangle.
   • Cosine ($\cos$): This looks at the side next to the angle compared to the longest side (hypotenuse).
   • Tangent ($\tan$): This compares the side opposite the angle to the side next to it.

2. Everyday Uses:

   • These concepts aren’t just for triangles. You can find them in many areas like physics, engineering, and even graphic design!

3. Problem-Solving Skills:

   • Getting a good grip on these ideas will give you helpful tools for solving tough problems later on, whether in school or on tests.

So, taking time to understand sine, cosine, and tangent is important. It will build a strong base for everything else in math that you will learn next!
