and calculus approach??I'm not sure about that. Using Snell's law was a clever idea, but maybe you should check with some conventional calculus.

If you got the answer using Snell's law, then great. That was very good.and calculus approach??

is calculus approach has something to do with properties of right angle and Pythagoras theorem?I'm not sure about that. Using Snell's law was a clever idea, but maybe you should check with some conventional calculus.

ohk moving on to next ques thanks for help :)If you got the answer using Snell's law, then great. That was very good.

Using calculus you need to minimise ##(1 + \frac w v) \sec \alpha - \frac u v \tan \alpha##. Which you do by usual differentiation method.is calculus approach has something to do with properties of right angle and Pythagoras theorem?
