- Sides of right triangles: Your friendly hypotenuses, opposites, and adjacent- Sine: Your very first trig function
- Cosine: Along with sine, cosine is a fundamental trig function- Tangent: Another important trig function (like sine and cosine)- Components (and cops): Find legs of right triangles, and don't get pulled over!- Sec, Csc, and Cot: Secant and friends (three more trig functions)
In a right triangle, the side opposite of the right angle is called the hypotenuse, and the other two sides are called its legs.
Sine = opposites side / hypotenuses
Cosine = adjacent side / hypotenuse
Tan = opposites / adjacent
Sec() = 1/cos() or hypotenuse/adjacent
Csc() = 1/sin() or hypotenuse/opposite
Cot() = 1/tan() or cos()/sin() or adjacent/opposite
