Remembering what trigonometric functions mean can be a little challenging, but I have some tips that really helped me. Here are some ideas that you might like:

1. Use Catchy Phrases: Making up fun phrases can help you remember things better. For example, to remember the main functions:

   • Sine: Think "SOH" (Sine = Opposite / Hypotenuse)
   • Cosine: Think "CAH" (Cosine = Adjacent / Hypotenuse)
   • Tangent: Think "TOA" (Tangent = Opposite / Adjacent)

2. Draw the Unit Circle: Drawing the unit circle and labeling it can make it easier to see how these functions connect to angles. When you plot points, you will find:

   • $sin(\theta)$ is the same as the y-coordinate,
   • $cos(\theta)$ is the same as the x-coordinate,
   • $tan(\theta) = \frac{sin(\theta)}{cos(\theta)}$.

3. Understand Reciprocals: Knowing that cosecant, secant, and cotangent are the “flip” versions of sine, cosine, and tangent can help clear things up:

   • $csc(\theta) = \frac{1}{sin(\theta)}$,
   • $sec(\theta) = \frac{1}{cos(\theta)}$,
   • $cot(\theta) = \frac{1}{tan(\theta)}$.

4. Practice with Real Problems: Using these definitions in real-world examples helps make the ideas stick. The more you practice, the easier it gets!

Try these strategies, and soon you’ll be able to say those definitions without thinking twice!
