Sec 4.2 Trigonometric Ratios of Any Angle
If is any angle in standard position and P(x, y) is any point on the terminal arm of
is any point on the terminal arm of at a distance r from the origin.
Pythagorean Theorem: r2 = x2 + y2 or
a2 + b2 = c2
SOH CAH
Sec 4.6 Other Trigonometric Functions
Remember:
Sin = y/r
Cos = x/r
Tan = y/x = sin /cos
Csc = 1/sin
Sec = 1/cos
Cot = 1/tan = cos /sin
Ex. With a calculator graph:
a. y = tan x
b. y = tan 3x
c. y = cot x (y = tan x 1)
d. y = csc x
e. y = 2 csc x
