Answer:
The answer is below
Step-by-step explanation:
The trigonometric function of a quadrant angle can be gotten using a unit circle. After measuring the angle to the corresponding unit circle, the x coordinate is the cosine of the angle while the y coordinate is the sine of the angle.
sec(π): The angle π = 180°, corresponds to the point (-1, 0) on the x axis. Hence cosπ = x coordinate = -1, sinπ = y coordinate = 0
secπ = 1 / cosπ = 1 / -1 = -1
cotπ = cosπ / sinπ = -1 / 0 = undefined
tanπ = sinπ / cosπ = 0/-1 = 0
