how do I solve this
note that I am not looking for about 53 degrees
I believe I'm suppose to solve euler's formula for x
sin (x) = (e^(ix) - e^(-ix))/(2i)
where x is in radians
hence I would do something like this
sin (x) = (e^(ix) - e^(-ix))/(2i) = 4/5
(e^(ix) - e^(-ix))/(2i) = 4/5
solve the equation above for x
this is were I need help if somebody could just show me quickly how to do this that would be great!!!
If I remeber correctly I need to use cis(x) or something right?
