Unit Circle Notes

VERY IMPORTANT ***The Quicker you learn this stuff the better off you will be*** sin Ө = y cos Ө = x (x, y) = (c, s)

Examples sin 45º sin 270º cos 270º tan 45º sin tan cos sec 30º csc 330º cot 0º

Degree / Radian Conversion Example: Convert 30° into radians Convert into degrees

Convert: 90º to radians 45º to radians to degree

UCQ1 Everyday this week you will have a Unit Circle Quiz. Today is just the 4 quadrant angles…you should already know these from Alg 1  Label all four BOLD points with coordinate pt, angle measure, radian measure…

Lots of Practice! Worksheet – Trig Values and Conversions
