Prove that for any prime positive integer p,√p is an irrational number |
| Answer» If possible,let √p be a rational number.also a and b is rational.then,√p = a/bon squaring both sides,we get,(√p)²= a²/b²→p = a²/b²→b² = a²/p [p divides a² so,p divides a]Let a= pr for some integer r→b² = (pr)²/p→b² = p²r²/p→b² = pr²→r² = b²/p [p divides b² so, p divides b]Thus p is a common factor of a and b.But this is a contradiction, since a and b have no common factor.This contradiction arises by assuming √p a rational number.Hence,√p is irrational. | |

|
Answer» There are some typing mistakes because i am not wellLater i will explain again Archana SarodeVery good question1. From above figure you can find all trigonometrical ratios .of 30, and 602. For 45 AB=BC so it is easy to find all ratios I hope it is easy for you sin45=cos45=1/{tex}\\sqrt 2{/tex}cos0=1,tan45=13. For 90 if {tex}\\angle{/tex} C=90 then AB=AC and BC=0 SO sin 0=0, cos0=1,tan90=inf4 For 0. If {tex}\\angle{/tex} C=0 then BC=AC and AB=0 sin90=1 ,cos 90=0 tan 0=0The detail calculation I leave for students\xa0 |
