In order for tan x = 0, sin x must be = 0 <span>sin x = 0 at 0 degrees and 180 degrees </span> <span>so, tan x = 0 at 0, pi </span> <span>as for the period being pi, you need to have tan x be negative and positive </span> <span>so remember the acronym All students take calculus ( ASTC) for where they are positive. </span> <span>tan x is negative in Quadrant II and positive in Quadrant I, since it just repeats after that, the period therefore must be Pi.</span>
The 28% rule states that you should spend 28% or less of your monthly gross income on your mortgage payment (e.g. principal, interest, taxes and insurance). To determine how much you can afford using this rule, multiply your monthly gross income by 28%
