Trigonometry Is the Science, or Not, the Science of Triangles

i got to trigonometry before i got to calculus because my dad told me a little pneumonic, sin cosin tangent. So, trigonometry is the science, or not, the science ystem, the math of triangles. I love it. It's awesome. That was cool. And all comes time for calculus. Let's don't use the big words. Let's just imagine things in our heads. But let's just think about that squiggly line. Is is what that's called.
