i even? I assume that means "is even"
even means reflects about the y axis right?
if f(-x) = f(x) it is an even function x^2 = (-x)^2

cos is an even function and sin is an odd function in general....just recapping my memory here :)
yep, that be always true
sin(x) cos(x) -sin(x) cos(x) ---------- = ----------- ???? 2tan^2(-x) -2tan^2(x)
i think I messed up that tan^2(x) part lol hold on
2tan(x)tan(x) = 2-tan(x)-tan(x) = 2tan^2(x) its (+) on the bottom and (-) up top; it aint even then
"All Students Take Calc" All positive in 1st quad Sine positive in 2nd quad Tangent positive in 3rd quad Cosine positive in 4th quad
yeah, it's not even it comes out neg
well of course tan is odd....it looks like x^3 lol right?
lool so taaan
