Analytic Geometry/Calculus
We didn't go over the perpendicular form in class, only the parallel. Find the general form of the equation of the plane passing through the point and perpendicular to the specified vector or line.

First separate it into 3 ⌠ 2⌡(2x^2/x^2) dx + 3 ⌠ 2⌡ 5x^-2 dx = ........ I'm sure you can continue the process. The answer is 17/6

Trig
Use Lemma sin m + sin n = 2sin(m+n/2)cos(m-n/2) cos m + cos n = 2cos(m+n/2)cos(m-n/2) We get (sin m +sin n)/cos m + cos n) = sin(m+n/2)/cos(m+n/2) = tan m+n/2)

Algebra
Okay, so your basic equation for perimeter is P= 2l + 2w So if your l=4w, then you're just going to substitute your values-> P=2(4w)+ 2w Hope this helps XD
