Periodic Functions Special Right Angles

s = short leg

l = long leg

Properties Of Sine Functions

|a| = amplitude

b = number of cycles (0 to 2pi)

Quadratic Functions

ax2

Quadratic term

bx

Linear term

c

constant term

Exponential Growth & Exponential Decay

b= growth factor

r= increase in rate

e & Its Importance

A= amount in account

P=principal (what you start with)

r = rate in interest (annually)

t= time (in years)

Unit Circle

radian 2pi, tangent 0

radian pi/6, tangent sqrt 3/3

radian pi/4, tangent 1

radian pi/3, tangent sqrt 3

radian pi/2, tangent undefined

radian 2pi/3, tangent -sqrt 3

radian 3pi/4, tangent -1

Sine, Cosine, Tangent Mazimun & Minimum

Area= length times width

Trigonometric Identities Angle Identities Identities Logarithms

b is not equal to 1

b must be positive

log of 0 or negative number = undefined

log= log base 10

Log Are Inverses Of Exponentials Properties Of Log

WATCH OUT FOR ERRORS

logb a/logb c does not equal logb a/c

logb a times c does not equal logb a times logb c

Expanding Log

left to right = expand

right to left = simplify

Natural Log Solving Log Equations Pairs Of Relations are Inverse Of Each Other
