## anonymous 5 years ago Quick Trig Help... Need help understanding a small point!

1. anonymous

$16\sqrt{2}(1-i) = 32(1/\sqrt{2}-i/\sqrt{2})=32(\cos (\pi/4)+isin(\pi/4))$ I get all of it APART from the + isin(pi/4), where did the "+" come from? Thanks!

=32(cos(π/4)+isin(π/4)) Last part seems to have cut off...
