how do you express arctan in terms of basic trigonometric functions?
I'm having difficulty solving the following equation which helps locate the angles in young's double slit experiment. Currently I'm using a graphical method.
The equation is:
=
a, b and C are constants.
I tried expressing in terms of .
However, = ±
And I'm not sure how to deal with the ±, given that I would like to make θ the subject, where 0 < θ < .
Ok so i used the theorem and ended up with:
=
Yeah I learned how to use the notation.
