In this exercise we will use the knowledge of equation of the line plus the knowledge of logarithm, like this:
First, we have the following values informed, such as:
- y = 512
- a = 8
- x = 3
Knowing that the formula for the equation of the line is given by:
The logarithm form will be:

Step-by-step explanation:
1. All the trigonometric values can be found using the unit circle. See attached table.
2. Graph:

3. All trig functions are periodic functions. The period of secant and cosecant is 2π. The period of cotangent is π.
4. Using the table from step 1 and the graph from step 2, secant has a domain of x ≠ pi/2, 3pi/2 and a range of x ≤ -1, x ≥ 1. Cotangent has a domain of x ≠ 0, pi, 2pi and a range of -∞ < x < ∞.
5. Graph:

Cosecant has the same graph as secant shifted π/2 to the right. So they have different domains, but the same range.
