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
1.$\displaystyle sin x = 1/\sqrt{2}$
$\displaystyle x = Asin(1/\sqrt{2})$
using a calculator, i found that $\displaystyle Asin(1/\sqrt{2})=.785398...$
I divided this number by pi and got 1/4
so the answer is $\displaystyle \frac{\pi}{4}$
2. $\displaystyle sin x = .35$
$\displaystyle x = Asin(.35)$
using a calculator, i found that $\displaystyle Asin(.35)=20.487......$
so the answer is 20.5 degrees
