Homework Statement
[itex]f'_x = kx_k, k = 1, 2, ..., n[/itex]
The Attempt at a Solution
The partial should be f(sub)x(sub)k, as in, the partial derivative of [itex]f[/itex] with respect to [itex]x_k[/itex]. I wasn't sure how to represent that using TeX.
I'm honestly at a complete loss here, because I'm not entirely sure what the subscripts refer to. I suppose if [itex]k = 1[/itex], then the derivative of [itex]f[/itex] with respect to [itex]x_k[/itex] [itex]= 1x_1[/itex], but that tells me absolutely nothing because I don't even know what that [itex]x_1[/itex] refers to...
Any help would be much appreciated!
