Soh Cah Toa

Fill in and solve for the trig functions

Types of triangles

60:30:90 and 45:90:45

When there's a missing side you

Cosø=(X/H:A:O) or Cosø=(H:A:O/X)

When you have a missing angel you

Tan^-1 * (O/A) =ø

When you have two triangles with depression or elevations you

Find the Tan:Cos:Sin of it so you get the lenght then you subtract the lenght of thr two for desired lenght

DMS

56.735


.735 * 60


44.1


.1 * 60


So 56.735 = 56*44'6"

DMS

32*5'28"


5/60


28/3600


= 32.091

DEG -> RAD

120 * Pie/180 = 2Pie/3


RAD -> DEG

5Pie/6 * 180/Pie = 150


Coterminal and Reference

+\- 360 & Get under 90

Arc Lenght


S=RØ MUST BE IN RAD

Area Of Sec

A=1/2 R^2 Ø

Trig Val

X,Y


R= Radical X^2 + Y^2



Draw it out

Exact Val

Find Ref and turn into coordinates


Cos = X


Sin= Y
