"Understanding Trigonometry"

I admit I have no idea about what Trigonometry is? Do any of you truly understand it? I can hardly spell the word without spell-check, Let alone try and explain what it means. On the other hand I have a lot of things that I can't begin to understand. How do the birds fly so close to each other by the hundreds and not collide? Who or what guides their every move and action? Fish do the very same thing! They look like Olympic synchronized swimmers. We don't need to know some things but accept and honor their specialness.God is after all the greatest designer of all! Verses: Gen 2 (all) Col 1: 15-20 Psalm 148(all)
