Snell's law, critical angle & refraction
According to Snell's law
n1sin(θ1) = n2sin(θ2)
If θ1 is θc, then θ2 = 90 degrees.
So sin(θc) = n2/n1
When I look up Snell's law on Wikipedia it says
\frac{\sin \theta_1}{\sin \theta_2}=\frac{v_1}{v_2}=\frac{n_2}{n_1}

factorise the equation
I assume you're being asked to factorise this expression or alternatively find the roots of f=0. Since the constant term is zero, there's a factor of x (equivalently, x=0 is a root). So f = x(x^
2+4x+3). You can find the roots of the quadratic x^2+4x+3, for example, by the formula, and they are -... | {"url":"http://mathhelpforum.com/advanced-algebra/777-factorise-equation.html","timestamp":"2014-04-17T20:33:57Z","content_type":null,"content_length":"30488","record_id":"<urn:uuid:96f380f9-33cd-4efc-859f-9406b81186ce>","cc-path":"CC-MAIN-2014-15/segments/1397609530895.48/warc/CC-MAIN-20140416005210-00153-ip-10-147-4-... |
