I'm doing second year calculus at uni. It's been challenging, but is overall very interesting.
When dealing with trigonometric functions (sine, cosine, tangent) these terms are shortened, and expressed with a variable. Usually, you'll see sin(x), tan(c) etc.
If I'm lucky, sometimes the problem will be cos(y), which always makes me smile.
the standard error of x multiplied by y = se(x)*y
ReplyDeleteOh man! That's awesome! Is that a stats/econo thing?
ReplyDeleteIs it sexy? cos(y) isn't really that cosy. About the same as any other trig function really
