Question

Arccos (-1) + arcsin 0

Answer 1

Arccos (-1) = пи
arcsin 0 = 0
Получаем:
пи + 0 = пи = 3.14.

Answer 2

To calculate the expression $\arccos(-1) + \arcsin(0)$, you can use the properties of trigonometric functions and their inverse functions.

1. $\arccos(-1)$: The arccosine function ($\arccos(x)$) gives the angle whose cosine is equal to $x$. When $x = -1$, the angle is $180^\circ$ (or $\pi$ radians) since $\cos(180^\circ) = -1$.

2. $\arcsin(0)$: The arcsine function ($\arcsin(x)$) gives the angle whose sine is equal to $x$. When $x = 0$, the angle is $0^\circ$ (or $0$ radians) since $\sin(0^\circ) = 0$.

Now, add these two angles together:

$\arccos(-1) + \arcsin(0) = 180^\circ + 0^\circ = 180^\circ$

So, the result is $180^\circ$, or equivalently, $\pi$ radians.
