I'm about to go insane because I don't understand the answer to the following problem: Find the first value of t after t=0 where v(t)=10 sin(1000 * pi * t + 30) reaches its peak value. Note: degrees not radians. I arrive at 60/(1000*pi) but they get approx: 0.333*10^3. Am I overly tired or are they wrong?

Best ResponseYou've already chosen the best response.0Calc or precalc? If you know about derivatives, this shouldn't be too difficult. The precalc approach isn't too bad, though.
