and then the direction (a,b,c) would be point on the line or would it just be (a,b,c)?

so do i sub in a point for t in the domain? and that will give <xo,yo, zo> and then how do i find the direction <a,b,c>.

x-xo/a=y-yo/b=z-zo/c

y(t) is the parametric curve, and i proved its a straight line by proving the curvature of the line. the "f" is supposed to be of

[b]1. if y(t)= (a/t, b/t, c/t) [b]2. Prove that this curve is a straight line. Find the equation of the line [b]3. i found the first part without a problem, i just am not sure how to find the equation f the line.

hey! so i sorted out the first part but how do i axctually prove that Li-1 (x) is equal to 1/(1-x)^2?

let nε Z. the polylogarithm functions are a family of functions, one for each n. they are defined by the following taylor series: Lin(x)= Ʃ xk/kn 1.calculate the radius of convergence [b]3. when i attempted this part, i couldn't use theratio or root test, so by comparison i got R=∞...
