See combined graph.

#### Explanation:

tan and cot are reciprocal functions.

See the combined graph of y = tan x and y = cot x, to realize that

each is the reciprocal of the other.

graph{(y- tanx )(y - cot x )(y^2-1)=0}

They meet at

Separate graphs. for y = tan x and y = cot x:

graph{y-tan x = 0}

graph{y-1/tan x = 0}
