1. ## x in deg. and rad. in terms of sin

Hi I need help with the following please?

Find X in radians, in terns of pi: sin x = 1/radical 2

Fine X in degrees, to nearest tenth: sin x = .35

THANK YOU

2. ## Inverse sin

1. $sin x = 1/\sqrt{2}$

$x = Asin(1/\sqrt{2})$

using a calculator, i found that $Asin(1/\sqrt{2})=.785398...$

I divided this number by pi and got 1/4

so the answer is $\frac{\pi}{4}$

2. $sin x = .35$

$x = Asin(.35)$

using a calculator, i found that $Asin(.35)=20.487......$

so the answer is 20.5 degrees
