Use the unit circle to evaluate the six trigonometric functions of θ = -π.

Sin θ=
Cos θ=
Tan θ=
Csc θ=
Sec θ=
Cot θ=

sin=0

cos=-1

tan=0

csc=undefined

sec=-1

cot=undefined

Step-by-step explanation:

On the unit circle, . The sin of theta is therefore 0, the cosine is -1, and the tangent is 0/-1=0. Since the following functions are just the reciprocals of the previous ones, the cosecant is 1/0=undefined, the secant is 1/-1=-1, and the cotangent is 1/0= undefined. Hope this helps!

for the points! : )
