## I am majoring in petroleum geology not engineering, do I have to take the course trigonometry?

I am not majoring in Petroleum Engineering as many would mistaken. I need some clarification on some of my classes that I’m taking because I am horrible in math especially trig.

Yes you will need to learn trigonometry for geology. Think maps and how you have to triangulate areas… You’ll need more advanced mathematics than just trigonometry, but seriously, trigonometry is sooo simple (it does just take practice).

The three most important things I can say about trigonometry:

1st: ASTC (a short trig course). Read this counter clockwise on a coordinate system for each quadrant and it will tell you if All, just the Sin,just the Cos, or just the Tan function are positive in those quadrants.

2nd: Unit Circle. A circle with radius one at the origin will give you the values for sin and cosine as you rotate around it from the positive x-axis. Sin measures Y and cosine measures X coordinate. Tan = sin/cos and will give you the slope of the circle at that angle.

Practice. You will need it for Calculus and other classes. Don’t sell yourself short. You have probably not been taught it very well. You probably won’t need it in the real world but….
