Hi Everyone

This is for my physics assignment but it is maths

I have a formula n1sin1Ө=n2sin2Ө

Where:

n1 = 1

n2 =?

sin1Ө = 44

sin2Ө = 48

An my answer should be or close to 1.48. I can't get it.

Help would be good.

Thanks.(Nod)

Remember that the image of the function $\displaystyle sin(x)$ is always between $\displaystyle [-1,1]$ so $\displaystyle sin (1\theta) $ and $\displaystyle sin (2\theta)$ can't be 44 and 48 !.

The

**range**of the sine function is [-1, 1]; meaning, when you take the sine of any angle it's going to be a number between -1 and 1, so to say that

$\displaystyle \sin 1\theta = 44$ and $\displaystyle \sin 2\theta = 48$ is impossible. Can you double-check the assignment and see how**exactly**the problem is worded?

I think it does...

Oh, maybe I've just made a mistake with the image word, in spanish range and image (rango e imagen) are equivalent, so maybe I just didn't make my point clearly. In that case, my apologies.

Maybe my results are wrong, but even then I should get close to it because my results were quite good.(Nod)
