Oxana [17]
Answer:
The answer is D
Step-by-step explanation:
To be a function, you cannot have the same x values.
1.(√3)+(√2)
2.(√2)+(√5)
3.(√5)-(√3)
4.(√9)+(√2)
5.(√5)+(√4)
6.(√10)-(√3)
7.(√4)-(√2)
Cuz √[(a+b)±2√(ab)]=(√a)±(√b)
Step-by-step explanation:
sec x − cos x
Secant is the inverse of cosine:
(1 / cos x) − cos x
Find the common denominator:
(1 / cos x) − (cos² x / cos x)
Subtract:
(1 − cos² x) / cos x
