See graphs and explanation.

#### Explanation:

For graph of y = f(x), where f involves inverse trigonometric

functions, use the x-explicit inverse

both are the same.

Graph of

graph{x tan y+1=0 [-3.14, 3.14, 0 3.14]}

For the limits, as

Ax

The y-intercept js are

Extended graph for

+-3... , with both x and y without limits.

graph{x tan y+1=0 [-50 50 -25 25]}
