							actually sin(x) doesnt have period pi but 
sin(x)=mode of (sin(x+pi)
cos(x)= mode of cos(x+pi)
so there are repetition of value but sign are different
and when we divide them sign cancel
so tan(x) is separate than tan(x)
you can consider cos(x) and sin(x) in same category of trigonometric function but tan(x) is different
