Answer:
1 – cosθ/1 + cosθ = secθ – 1/secθ + 1
Here, we know that secθ = 1/cosθ
Now,
1 – cosθ/1 + cosθ = secθ – 1/secθ + 1
1 – cosθ/1 + cosθ = 1/cosθ – 1 ÷ 1/cosθ + 1
1 – cosθ/1 + cosθ = 1 – cosθ/cosθ ÷ 1 + cosθ/cosθ
1 – cosθ/1 + cosθ = 1 – cosθ/1 + cosθ
Hence Proved!!

Answer:
all are functions except Relation 2
Step-by-step explanation:
If any input value (first of an ordered pair) is used more than once, the relation is not a function. Output values can be used as often as you like.
Only Relation 2 is not a function.
