Answer:
(a) sec²(θ) -tan²(θ) = 1
Step-by-step explanation:
The identity relation between sec(θ) and tan(θ) is ...
tan²(θ) +1 = sec²(θ)
__
When tan²(θ) is subtracted from both sides of this equation, the result matches the first choice:
sec²(θ) -tan²(θ) = 1
_____
<em>Additional comment</em>
This is a variation of the "Pythagorean" relationship between sine and cosine. There is a similar relation between cot²(θ) and csc²(θ).
X-c/2 = d
Multiply by 2 on both sides. Leaves us with:
x-c = 2d
Add 2 to both sides. Leaves us with:
x = 2d + c
Unless you have values to substitute into the variables, this is your answer:
x = 2d + c
