What is the amplitude for basic:cosxsinxtanxcscxsecxcotx
|
If Positive Then: cosx = 1sinx = 1tanx No amplitude EVERcscx No amplitude EVER secx No amplitude EVERcotx No amplitude EVER

|
Find all values for x for which these are true statements: 1) cosx = 02) sinx = 13) tanx = 0 4) cscx = 1
|
1) π/2 + k(π)2) π/2 + 2k(π)3) kπ4) π/2 + 2k(π)

Graph: y = 3sinx + cos2x π
|
|
|
Evaluate:Tan ( Sin-1 3/5)
|
Tan alpha = 3/4
|
|
The graphs of csc x and sec x each have periods of:
|
2π
|
|
Csc and sec are __________________ of sin and cos.
|
Reciprocals
|
|
What is the amplitude of sec and csc?
|
Zero because there is no longest or smallest value of y.
|
|
What does this mean?: y = tan-1x ory = arctanx
|
x = tan y and - π/2 < y < π/2(y is the angle between -π/2 and π/2 where tangent is x)
|
|
Give amplitude, period, and phase shift for: y = 3sin(2x + π/2)
|
Amplitude = 3Period = πPhase shift = - π/4
|
|
The graphs of: y = tan x and y = cot xeach have periods of __________
|
π (looks like 2 T's)
|
|
The tan curve passes through ____________
|
Origin

|
cot is ______ when tan is zero
|
Undefined
