Well it is a gateway to calculus, soon you’ll be able to be closer to understanding problems that include changing values like acceleration.
And "changing values" is progressive brainwashing. The Truth isn't variable; it's constant: 3 = 1. Epsilon-Delta = Epstein-Data! Trigonometry is all about the SIN OF XY — that's gay pornography and Greek pederasty being taught to your children as "math". SIN WAVES are Liberal Lewdness in Our Schools! Don't let your children be tangent to these dangerous curves!
