The things that i learnt this week are angles in standard position in quadrant 1, angles in standard position in all quadrants, the sine law, the cosine law.
s=o/h c=a/h t=o/a
SOH CAH TOA
(cos0)^+(sin0)^=1 cos^+sin^0=1
for any angle 0 in standard position, where 0=<0=<360, with terminal point P(x,y), the primary trigonometric ratios are defined as: cos0=x/y
sin0=y/r
tan0=y/x
In any ABC c^=a^+b^-2ab cos C
For any ABC a/sinA=b/sinB=c/sinc and sinA/a = sinB/b =sinc/c
