Best ResponseYou've already chosen the best response.1yeah ... that is the problem. you haven't advanced to the point of doing this. let f(x) = cos(x), what is value of f(0)

experimentX

Best ResponseYou've already chosen the best response.1yep ... if f(x) = sin(x) ,,, then what is f(pi/4) ??

experimentX
 one year ago
Best ResponseYou've already chosen the best response.1yes ... what is f(3pi/4) ??

onegirl

Best ResponseYou've already chosen the best response.1what is that point?

experimentX
 one year ago
Best ResponseYou've already chosen the best response.1we talked about that in the above posts. check again ... the point is pi/2

onegirl

Best ResponseYou've already chosen the best response.0so it reached 0 at pi/2

experimentX
 one year ago
Best ResponseYou've already chosen the best response.1no ... the derivative is zero at pi/2
