period formula

2π/b (pi/B for tanx)

angular speed formula

w = radians/time

linear speed formula

v = r * w

vertical asymptotes for tangent functions

The vertical asymptotes for tangent functions occur at odd multiples of π/2, specifically at x = (2n + 1)π/2, where n is an integer.

x-intercepts for tangent functions

The x-intercepts for tangent functions occur at integer multiples of π, specifically at x = nπ, where n is an integer.

law of sines formula

sinA/a = sinB/b = sinC/c

law of cosines formula

c² = a² + b² - 2ab cosC

csc theta =

1/sin(theta)

sec theta =

1/cos(theta)

tan theta =

sin(theta)/cos(theta)

cot theta =

cos(theta)/sin(theta)

pythagorean identities

sin² theta + cos² theta = 1
tan² theta +1 = sec² theta

cot² theta +1 = csc² theta

General Form y=A*f(B(x-c))+D

A: multiply y-coordinate by A; vertical stretch/compression

B: divide x-coordinate by B or multiply by reciprocal of B; horizontal stretch/compression

C: add c to x-coordinate

D: add D to y-coordinate
