Finding angles in all four quadrants
Cards in this deck (4)
- 1Methods of finding angles in all four quadrantsGraphs
CAST diagram - 2Reference frame for angles on a Cartesian planeAngles measured from the positive side of the x-axis
Anticlockwise = increase in angle - 3How to solve equations where a trig function = a constantUse the inverse function on the modulus of the constant to find an angle within the range \(0 \leq \theta \leq 180^o\)
Use the CAST diagram / the relevant graph to find the - 4Equations with more than one trig functionUse identities, equivalences and substitutions to reduce it to one trig function and a constant then solve for the constant
