Question

Solve for x. Round to the nearest hundredth.

sin x ≈ 0.965926

This is a practice problem. It says the answer is 75 degrees, but i don't understand how you get it?
Please help.

Answer 1

x=arc sin(0.965926)
use ur calculator

Answer 2

what's x=arc? I got sin(.965926) = .0168577904

Answer 3

arcsin and sin^-1 are the same. Have you seen either of those notations?

Answer 4

i've seen sin

Answer 5

Well, arcsin and sin^-1 (pronounced "sine inverse", and the "-1" is not an exponent) are simply inverse functions of the sine function.

If y = six X then arcsin y = x.

"Take the sine of an angle and you get a number (sin 30 = 1/2) Take the arcsin of a number you get an angle (arcsin (1/2) = 30 degrees)"

Memorize that! Take your time. Be able to recite it in the dark and cold, even when you're hungry.
