How do you graph
abs(y)=x

• precalc -

or abs(y)>= x

• precalc -

| y | ¡Ý x

• precalc -

If x = |y|, then you have the following function:

x = {
y, y>0
-y, y<0}

So your graph looks like y = x and y = -x graphed together, both with the domain [0, infinity)

would this be a correct proof of the cauchy-schwartz inequality: abs=absolute value abs(u*v) is less than or equal to abs(u)*abs(v). Then you divide both sides by abs(u)*abs(v) so that you get cos(theta) is less than or equal to 1.
