How to find csc sec and cot on unit circle
Asked by admin @ in Mathematics viewed by 263 People
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=
Answered by admin @
Answer:
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!
