Question

Find the value of Arc cos 0

Answer 1

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

$x=\frac{\pi}{2}$

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

Answer 2

Answer:

d. π/2

Step-by-step 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:

$90\pi/180=\pi/2$
