y=tanx

Domain:-

R-{(n*180) + 180/2),n ε Z(integers))}

but how can n belong to integer because if n belong to integer than an angle would be negative and i dont think so that negative angles are there,i think that in place of (integers),natural nos. should come.but why they dont put natural nos. in place of integers,there??
