Maths Trig Graphs
Notes
📝
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
