- Convert to DMS
convert each able in degrees to radians
multiply by pi/180
convert each angle in radians to degrees
multiply by 180/pi
distance (s) equation
s=degree x radius
Area formula
A=1/2 r^2 degree (make sure degree is in radians)
angular speed
w=degree/time (degree in radians)
linear speed
v=wt (w in radians)
(x,y) equals
(cos, sin)
Find the exact value. No calculator. trig functions with pi/radians
Draw on graph, will be straight line, and 0, 1, or -1
45, 45, 90 triangle
1, 1, square root 2
30, 60, 90 triangle
1, square root 3, 2
adding sin/cos/tan
draw and find both and add
find the exact values of the six trigonometric functions of the given angle. If any are not defined, say “not defined”. Do not use a calculator
draw and determine, if negative go clockwise
a point on the terminal side of an angle in standard position is given. Find the exact value of each of the 6 trigonometric functions of angles.
- draw point
- Fill in triangle using Pythagorean theory
- Solve
cos to sec and tan to cot
flip before rationalize
name the quadrant in which angle lies
ASTC in C shape
tan is
sin/cos
EO properties sin and csc
sin(-d)= -sind csc(-d)= -cscd
EO properties cos and sec
cos(-d)=cosd
sec(-d)= secd
EO properties tan and cot
tan(-d)= -tand cot(-d)= -cotd
Use the EO properties to find the exact values of each expression. NO calculator
- EO properties
- use triangle to find values
use properties of the trigonometric functions to find the exact value of each expression. No calculator
sin^2d + cos^2d = 1
tan^2d + 1 = sec^2d
cot^2d + 1 = csc^2d
