Sine law is not for computation only; it is one of the coolest theorem that can solve almost anything! It is like Fubini's principle of Geometry!
BTW try to prove this one:
In $\triangle ABC$, $P$ lies on $BC$ (possibly on the extensions). Prove that, \[ \frac{BP}{PC}=\frac{AB \times \sin \angle BAP}{AC \times \sin \angle PAC}\]

হাসিব, মোবাইলের জন্যে তো পিডিএফ রিডার আছে... গুগল করে তোমার সেটে ইউজ করা যাবে এমন কোন একটা ইন্সটল করে দেখ...
