### What is the value of Arcsin 0?

• A.

0

• B.
• C.
• D.
A. 0
Explanation
The value of Arcsin 0 is 0 because the arcsine function returns the angle whose sine is equal to the given value. Since the sine of 0 is 0, the arcsine of 0 is also 0.

### What is the value of Arccos(-1)

• A.

0

• B.
• C.
• D.
B.
Explanation
The value of Arccos(-1) is 180 degrees or Ï€ radians. This is because Arccos is the inverse function of cosine, and cosine of 180 degrees or Ï€ radians is equal to -1.

### What is the value of Arccos0

• A.

0

• B.
• C.
• D.
C.
Explanation
The value of Arccos0 is 90 degrees or Ï€/2 radians. This is because the arccosine function gives the angle whose cosine is equal to the given value. In this case, the cosine of 90 degrees is 0, so the arccosine of 0 is 90 degrees.

### What is the value of Arccot(0)

A.
Explanation
The value of Arccot(0) is equal to Ï€/2. This is because the arccotangent function returns the angle whose cotangent is equal to the given value. Since the cotangent of Ï€/2 is 0, the arccotangent of 0 is Ï€/2.

• B.

25

• C.

125

• D.

625

C. 125
Explanation
The pattern in the given sequence is that each number is obtained by multiplying the previous number by 5. Starting with 5, we have 5 * 5 = 25, 25 * 5 = 125, and 125 * 5 = 625. Therefore, the missing number in the sequence is 125.
