Step-by-step explanation:
A
= 3
Since 3 × 3 × 3 = 27
B
= ± 5
Since 5 × 5 = 25 and - 5 × - 5 = 25
C
= ± 9
Since 9 × 9 = 81 and - 9 × - 9 = 81
D
= 1
Since 1 × 1 × 1 = 1
Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identity
tan²x + 1 = sec²x ⇒ tan²x = sec²x - 1
Consider the left side
sec²x × tan²x + sec²x
= sec²x(sec²x - 1) + sec²x ← distribute and simplify
=
x - sec²x + sec²x
=
x = right side ⇒ verified
