- 1Quadratic formula-b± square root of -b^2 -4ac
2a - 2Sine RulesinA/a = sin B/b = sin C/c
( (missing angle),
(use sin inverse nearing to end))
a/sinA = b/SinB c/sinB
(missing side )
Use when you are given an angle
and a supporting side - 3cosine rulea^2 = b^2 +c^2 -2bcCosA
(the 2 given sides MUST
make up a given angle.)
