Our standard form: y = a sin b( x – h ) + k
LESSON: To Use The Phase Shift Part 2 Our standard form: y = a sin b( x – h ) + k Sometimes you have an equation that looks like this: We need “x” alone, what can we do? We just factor out the ½ ! And we are ready to graph!
5
What about this: This just means: Which becomes: And we are ready to graph!
6
We can harness the POWER OF ONE!
Sometimes you have an equation that looks like this: We need “x” alone, what can we do? We can harness the POWER OF ONE! We need a denominator of “2”, so multiply π by Now, they have something in common, that can be factored out. And we are ready to graph!
7
You can always check by just distributing the fraction back in!
Let’s try some more (just “fix” the equation): And we are ready to graph! You can always check by just distributing the fraction back in!
