@ -25,11 +25,11 @@ There are 4 general functions:
| $$ y = A * sin(B(x - \frac{C}{B})) + D $$ | $$ y = A*cos(B(x - \frac{C}{B})) + D$$ | | $$ y = A * sin(B(x - \frac{C}{B})) + D $$ | $$ y = A*cos(B(x - \frac{C}{B})) + D$$ |
How to find the:
| Variable | Meaning | - Amplitude: $|A|$
| -------- | --------------------------------------------------------------------------------------------- | - Period: $\frac{2\pi}{B}$
| $A$ | The amplitude of a function can be found by taking $\|A\|$. The sign flips it over the x axis | - Phase shift: $\frac{C}{|B|}$
| $B$ | Horizontal, or phase | - Vertical shift: $D$
$$ y = A * \sin(B(x-\frac{C}{B})) $$ $$ y = A * \sin(B(x-\frac{C}{B})) $$
