Answer :
Answer:
- cos(π/2)
- sin(0)
- tan(π)
Step-by-step explanation:
You want to know which trig functions on the given list have a value of zero.
Trig functions
Sine
The sine function is zero at x=0 and multiples of π.
Cosine
The cosine function is zero at x = π/2 and for odd multiples of π.
Tangent
The tangent function is zero at x=0 and multiples of π. It is zero in the same places the sine function is zero.
List values
These values are zero:
- cos(π/2)
- sin(0)
- tan(π)
These function values are something different:
- cos(0) = 1
- sin(3π/2) = -1
