Addition of Ordinates for Circular Functions (VCE SSCE Mathematical Methods): Flashcards

Adding y-values of two functions at each x-value to graph their sum

Audio compression and signal processing

$g(x)$ - sum passes through same point as $g(x)$

$f(x)$ - sum passes through same point as $f(x)$

Greater than either individual function

More negative than either individual function

Sum lies between the two functions

Look for values where $f(x) + g(x) = 0$

Add y-values of component functions at each x-value

Where functions have maxima, minima, or zeros
