Question

evaluate the Acrsin(1)?

Answer 1

se sine is -1".
---
Then you have to know that sine is -1 when the


angle is 270 degrees or (3/2)pi radians.
----
If you know both of those things, you know the
answer to your problem is arcsin(-1) = 270 degrees.

Answer 2

but its the arcsin(1) not -1?

Answer 3

@KinzaN

Answer 4

\[\sin^{-1} (1)\] is what you're looking for--

Answer 5

it's 90 degrees or pi/2 radians.

Answer 6

yes but i am suppose to solve it using special right triangles?

Answer 7

or unit circles

Answer 8

Ah, I always think graphically. You'd use unit circle, though, I suppose.

Answer 9

it would be the point (0,1) which is on the y axis at 90 degrees?

Answer 10

On the unit circle, sin(1) is on the "point" (1, 0) where the angle is 0 or 2pi.
The inverse would be (0, 1) where the angle is pi/2 or 90 degrees.

Answer 11

Right. =D

Answer 12

ok and one more?

Answer 13

:D

Answer 14

What?

Answer 15

arctan(radical 3 over 3)

Answer 16

would it be 60?
