    How do I solve this trigonometry equation involving sine and cosine?

    going off of what he was saying, imagine for a second that the 2 wasn't there, so that you have sin(u)=0. For confusions sake, let's call it n now. So you've got sin(n)=0 Essentially saying the sign of some angle "n" equals 0 right? You should be able to figure out what that angle n is. If...

    Convert the polar equation into rectangular coordinates

    okay that was kinda harsh! But he's right, you're forgetting something in that r \neq x2+y2 what does r equal? Or maybe, what does r2 equal? :wink:

    Limit of a sequence with n as a variable, and to the power of n

    I didn't think i could because the whole thing is to the power of n, but i guess i wasn't thinking straight? Anyways, thanks again for the help I was just studying for my calc2 exam tomorrow and came across this one

    Limit of a sequence with n as a variable, and to the power of n

    Homework Statement Find the limits of the following sequences, if they exist. Justify your answers. [SIZE="6"]{(\frac{n-1}{n} [SIZE="6"] )^{n}[SIZE="6"]} ^{\infty}_{n=1} or maybe \sum^{\infty}_{n=1}(\frac{n-1}{n} )^{n} is clearer? Homework Equations I know the whole part that it's a...
