Steps = Period/4


x E (restriction) except for Tan


y E (min;max) except for Tan


Amplitude is distance from middle to range of graph except for Tan


Period = 360/k or 180/k

, Sx)=asin(kx-p)+q
C(x)=acos(kx-p)+q


● a = amplitude
Distance from the x axis
● k = period
Period = 360/k
● p = left and right translation
Inside bracket, always in degrees
● q = up and down translation
Outside bracket, always an integer



T(x)=atan(kx-p)+q


● a = vertical compresión
reflection from the x axis
● k = period
Period = 180/k
● p = left and right translation
Inside bracket, always in degrees, Asymptote shift!
● q = up and down translation
Outside bracket, always an integer




How to ?
1. Mode 7
2. f(x) insert what you see
3. Equals
4. Start and End would be found at end of equation eg : x E (
-360 ; 360 )
5. Steps = period/4
