Trigonometry

1. Sine, Cosine and Tangent

   • Cosine: cos(θ) = Adjacent / Hypotenuse
   • Sine: sin(θ) = Opposite / Hypotenuse
   • Tangent: tan(θ) = Opposite / Adjacent

2. Right Angled Triangle

   • We know the angle θ.
     • Adjacent is adjacent (next to) to the angle θ
     • Opposite is opposite the angle θ
     • The longest side is the Hypotenuse

3. Degrees and Radians
