Exact trig values method
WebA simple and clear illustration of how to derive these values, and the values themselves. Easy to use in the classroom, or print slides for crib sheets for learners. The specs require: '•know the exact values of sin θ and cos θ for θ = 0°, 30°, 45°, 60° and 90°. •know the exact value of tan θ for θ = 0°, 30°, 45° and 60 ’. WebTo find (or recall) the trig values for 45° angles: Draw a 45-45-90 triangle with short sides having lengths of either (a) sqrt (2) or (b) 1. Label the hypotenuse as having a corresponding length of either (a) 2 or (b) sqrt (2). From whichever triangle you have drawn (either Triangle (a) or Triangle (b)), read off the trig ratio you need.
