taylor holiday reflection #3

ill review more of the recent information for this reflection
but i must say the stuff we have seen is old news now
we know it
its simple for us to work with
but im nervous for whats to come with the last half of the school year

Degrees to Radians is: degrees*pi/180
Radians to Degree is: radians*180/pi

Unit Circle:
90 degs. = (0,1) pi/2
180 degs. = (-1,0) pi
270 degs. = (0,-1) 3pi/2
360 degs. = (1,0) 2pi


sin=y/r
cos=x/r
tan=y/x
cot=x/y
sec=r/x
csc=r/y

SOHCAHTOA:

S = sin
O = opposite angle
H = hypotenuse
(sin = opposite/hypotenuse)


C = cos
A = adjacent angle
H = hypotenuse
(cos = adjacent/hypotenuse)


T = tan
O = opposite angle
A = adjacent angle
(tan = opposite/adjacent)
