passing through origin....f(x) ε [-Π/4, Π/4]

not exactly sinusoidal ....

Domain=R
Range=[-pi/4 ,pi/4]
Roots=Same as sinx
Period=2pi
Odd function
y'=cosx/1+sin²x
y'=0 =>cosx=0 =>x=pi/2,3pi/2..........
y"(x=pi/2)<0 =>Maxima point
y"(x=3p/2)>0 =>Minima point

So it looks that graph is same as sinx.....[1]

it should be y=x/√(1-x²)

i have already mentiod taht period is 2pi sir..........[1]
