Best ResponseYou've already chosen the best response.0Coz f(x) have one half of the period of g(x) , f(x) have a period of pi. and f(pi/4) = 4 and they are both sine waves. f(0)=0 and because of period , x=pi f(pi) = 0 again. so f(x) = 4sin(2x)

Best ResponseYou've already chosen the best response.0we can assume f(x) =ASin(Bx) +C where A,B,C are variables x=0, f(x)=0 and when x=pi/4 f(x)=4 and when x= pi f(x) =0 so we can solve it for the three variables that way too

Best ResponseYou've already chosen the best response.0sorry i assigned f(x) as f(θ ) and g(x) as g(θ )

Best ResponseYou've already chosen the best response.0ok lets try from the beginning. It says both functions are sine functions. right? so f(θ ) takes the format of f(θ )= ASin(Bx)+C

Best ResponseYou've already chosen the best response.0I've never really learned that format....I just learned that "A" as you say is the amplitude, and B is period...what is C? O.o

Best ResponseYou've already chosen the best response.0\(g(\theta)=2~sin~2\pi~\theta\) eh?

Best ResponseYou've already chosen the best response.0just relax its easy . this is a graph ok? a graph of a sin function. according to θ ,y or f(x) change ok?
