Question

Laborious trigonometry question here! Help would be great :)

Answer 1

Evaluate the six trigonometric functions for the angle.
\[\theta=\frac{ 13\pi }{ 4 }\]

Answer 2

you might could use that the period of sin and cos and sec and csc is 2pi
and also the period of tan and cot is pi

Answer 3

you can use the unit circle to find sin/cos then use the following relationships
tan = sin/cos
csc = 1/sin
sec = 1/cos
cot = 1/tan
