6-4

Sooo I hope everyone had an awesome time at prom this weekend. I can’t remember if we did hyperbolas this week cause we only had one day of learning this week. The rest of the week we did aleks. So I’m just gonna do section 6-4 hyperbolas.

In the form x2/a – y2/ = 1 or –x2/a2 + y2/b2/

Parts of the equation
-Major axis : variable with larger denominator
-Minor axis: variable with smaller denominator
-Length of major: 2 square root non negative denominator
-Length of minor: 2 square root smaller denominator
-Vertex: square root non negative denominator if x is major (_,0 )and (-_,0); if y is major (0,_) and (0,-_)
-Other intercept: smaller denominator ( , ) Opposite of vertex
- Focus: focus2 = larger denominator and smaller denominator if x is major (focus,0) if y is major (0,focus)
-Asymtoles: y = +/-b/ax if x is major, y = +/-a/bx if y is major
