How Does Trigonometric Functions: Sine, Cosine, Tangent, Cosecant, Secant Work?

Imagine you're on a merry-go-round, trigonometric functions are like your friends who tell you where you are and how you’re moving as you spin around.

The Spin of Sine, Cosine, and Tangent

Think of a clock face, that’s like a circle. If you’re on the merry-go-round, imagine a line from the center to where you're sitting. That's your radius.

  • Sine is like your height above the ground as you spin.
  • Cosine is how far you are from the center along the ground.
  • Tangent is like a slide, it shows how steep your ride is, comparing your height to your distance from the center.

The Cool Friends: Cosecant, Secant

Now imagine your friends who love to flip things upside down:

  • Cosecant is just the opposite of sine, if sine tells you your height, cosecant tells you how many times bigger the radius is than your height.
  • Secant does the same for cosine, it compares the radius to your distance from the center.
