Question

2arccos0+3arccos1=???????

Answer 1

2arccos0+3arccos1=2х π/2+3х0= π+0= π

Answer 2

Let's solve the expression step by step:

1. arccos(0): The arccosine (inverse cosine) of 0 is 90 degrees or π/2 radians. This is because the cosine of 90 degrees (π/2 radians) is 0.

2. arccos(1): The arccosine of 1 is 0 degrees or 0 radians. This is because the cosine of 0 degrees (0 radians) is 1.

Now, let's substitute these values back into the original expression:

2 * arccos(0) + 3 * arccos(1) = 2 * (π/2) + 3 * 0 = π + 0 = π radians

So, 2arccos(0) + 3arccos(1) equals π radians.
