numerator
And the denominator is 0
They are a common factor and any common factor in the numerator and denominator of a ratio can be cancelled out.
If the numerator is 0 AND the denominator is not 0, then the ratio is 0. And cosine of 0 is 1.
It is the corresponding fraction.
It is a ratio.
Dividing the numerator and denominator by a common factor is how you simplify a fraction.
