Can you please tell me the reason behind this relation:
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??

Of course there are negative angles. All trig functions extend infinitely in the positive and negative directions.

can you give me an example related to it by just using the tan x and putting value in it?

Trignometric simple function:
can the tan of an angle be negative,if so,then how?

Physically, this would correspond to pointing your arm at an object that is 100 feet away horizontally and 100 feet down vertically. The angle is 45 degrees below horizontal and the tangent of the angle is the result of dividing the opposite side (100 feet vertical) by the adjacent side (100 feet horizontal).
