What happens to sine and cosine beyond 90°? Do they suddenly become meaningless? NO! Avinto reveals the unit circle mathematics' most beautiful tool for extending trig to ALL angles from 0° to 360° and beyond! A compass bearing of 270°? The angle of a negative rotation? All handled elegantly by the unit circle! You'll discover that trig ratios can be positive OR negative depending on which quadrant the angle falls in and the CAST rule tells you exactly which ones! This is the moment trigonometry expands from right triangles to the entire coordinate plane! Your trig mastery reaches a new level with Avinto!
