Step 1.2.1

Rewrite the equation as $\csc (x) = 0$ .

$\csc (x) = 0$

Step 1.2.2

The range of cosecant is $y \leq - 1$ and $y \geq 1$ . Since $0$ does not fall in this range, there is no solution.

No solution

Step 1.3

To find the x-intercept(s), substitute in $0$ for $y$ and solve for $x$ .

x-intercept(s): $None$

Step 2

Step 2.2.2.1.1

Rewrite $\csc (0)$ in terms of sines and cosines.

$y = \frac{1}{\sin (0)}$

Step 2.2.2.1.2

The exact value of $\sin (0)$ is $0$ .

$y = \frac{1}{0}$

Step 2.2.2.2

The equation cannot be solved because it is undefined.

$Undefined$

Step 2.3

To find the y-intercept(s), substitute in $0$ for $x$ and solve for $y$ .

y-intercept(s): $None$

Step 3

List the intersections.

x-intercept(s): $None$

y-intercept(s): $None$
