Hello PF users hope all is well!
I need a reminder of the formulas needed in order to get

"Sine of angle of incidence"

"Sine of angle of refraction"

And "Index of refraction".

The only information I have available now is

"Angle of incidence" And "Angle of refraction"

I'm guessing they're all along the lines of Snell's law

i hope you wish to know about calculating the refractive index of a medium through the info about angle of incidence and angle of refraction.
what is snell's law? and how it is applied?
and how to calculate sine of an angle.
its simple to draw a right angle triangle with base angle 'equal to angle of your choice' and take the ratio of perpendicular length with hypoteneuse , then you get the sine of that angle.
or go to the trigonometric table of sine of the angles and get values and calculate index of refraction = ratio of sine of the angle of incidence and refraction.

Thank you for the help, I can clearly recall how to calculate it.
