Using memory aids to quickly identify and solve trigonometric problems.
It is a two step process involving two skills.
First skill:
IDENTIFY THE TRIGONOMETRIC
ANGLES, SIDES and HYPOTENUSE in different orientations
Second skill:
IDENTIFY the MNEMONIC that finds the VALUE sought and contains VALUES given
Important: if x is an angle value given it will appear in one of these ways as sin(x), cos(x) or tan(x) in the mnemonics.
2 MNEMONICS to find sides given an angle
Oriental Hoisin Sauce O= HSIN(t)
Apes Hug Cozily A= HCOS(t)
1 MNEMONIC to find the angle given two short sides and no hypotenuse
TorNAdos Over America t =TAN-1(O/A )
Tornados has NA inverted to remind you it is the inverse tangent
