Best ResponseYou've already chosen the best response.0@Ishaan94 i plotted sin x+cos x its period is coming out to be 90, 4 lobes in 360....u are correct, its pi/2, not pi

Best ResponseYou've already chosen the best response.0@sauravshakya plot the sum, not individually, i also made that mistake and got pi, but its pi/2

Best ResponseYou've already chosen the best response.0THIS MAY ALSO WORK: IsinxI+IcosxI=IsinxI + Isin(90x)I

Best ResponseYou've already chosen the best response.0THAT CLEARLY SHOWS PERIOD MUST BE greater than or equal to 360 degree

Best ResponseYou've already chosen the best response.0BUT IT CANNOT BE greater than 360 degree as same pattern will repeat as the values of sin1 and sin 361 are same........ THUS the period is 360 degree.
