IS IT pi?

2pi, but how

So, the modulas sign makes great difference.

for simplicity, first try |sin x|+|cos x| @sauravshakya

well for that pi

|dw:1348660397213:dw|

@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

@sauravshakya plot the sum, not individually, i also made that mistake and got pi, but its pi/2

OK

THIS MAY ALSO WORK:
IsinxI+IcosxI=IsinxI + Isin(90-x)I

THAT CLEARLY SHOWS PERIOD MUST BE greater than or equal to 360 degree

CORRECT ?

yes, the period is 2pi
