Question

Find the value of Arc cos 0

Answer 1

d. π/2

Explanation:

1. You have the inverse trigonometric function
`Arc cos(0)`.

2. Enter into you calculator
`cos^(-1)(0)`, which is (in degrees)

`cos^(-1)(0)=90`°

3. This result in radians is:

`90\pi/180=\pi/2`

Answer 2

we are given

`arccos(0)`

we can also write it as

`arccos(0)=cos^(-1)(0)`

Let's assume arccos(0)=x

`cos^(-1)(0)=x`

now, we can take cos on both sides

`cos(cos^(-1)(0))=cos(x)`

`0=cos(x)`

we know that cos is zero at pi/2

so, we will get

`x=(\pi)/(2)`

so, option-D..........Answer
