Hello everyone! I'm confused on what i'm suppose to do here, I think i might got it though but i need to make sure...(adsbygoogle = window.adsbygoogle || []).push({});

Here is the problem and my work:

http://show.imagehosting.us/show/764032/0/nouser_764/T0_-1_764032.jpg

he let r(t) = f(t) i + g(t) j + h(t) k. So if i multiply this by itself, won't that make the vectors go away? because isn't (i)(i) = (j)(j) = (k)(k) = 1?

Thanks!
