1 ) cot x * sin x = cos x
(cos x / sin x) * sin x = cos x
cos x = cos x
Answer: B ) cot x = cos x / sin x
2 ) ( sin² x + cos² x ) / cos x = sec x
1/cos x = sec x
sec x = sec x
Answer: C ) cos² x + sin² x = 1

Answer:
4,321
Step-by-step explanation:
This is the answer because:
1) We know that if the number has to be big therefore, we have to put 4 in the thousands place because 4 is bigger than 3, 2, and 1
2) Next, 3 is the other biggest number, for that reason 3 is in the hundreds place
3) Then, 2 is the other bigger number; therefore, the tens place is 2
4) Finally, the last number remaining is 1, which is in the ones place
Therefore, the answer is 4,321
