Prove that root 3 is an irrational number |
|
Answer» Answer: Step-by-step explanation: LET us ASSUME on the contrary that \sqrt {3} 3 is a RATIONAL number. Then, there exist positive integers aa and bb such that \sqrt { 3 } =\dfrac { a }{ b } 3 = b a where, aa and bb, are co-prime i.e. their HCFHCF is 11 Now, \sqrt { 3 } =\dfrac { a }{ b } 3 = b a
\Rightarrow \quad 3=\dfrac { { a }^{ 2 } }{ { b }^{ 2 } }⇒3= b 2
a 2
\Rightarrow \quad 3{ b }^{ 2 }={ a }^{ 2 }⇒3b 2 =a 2
\Rightarrow \quad 3|{ a }^{ 2 }\quad \quad \left[ \because 3|3{ b }^{ 2 } \right]⇒3∣a 2 [∵3∣3b 2 ] \Rightarrow \quad 3|a\quad \quad ...\left( i \right)⇒3∣a...(i) \Rightarrow \quad a=3c⇒a=3c for some integer cc \Rightarrow \quad { a }^{ 2 }=9{ c }^{ 2 }⇒a 2 =9c 2
\Rightarrow \quad 3{ b }^{ 2 }={ 9c }^{ 2 }\quad \quad \left[ \because { a }^{ 2 }=3{ b }^{ 2 } \right]⇒3b 2 =9c 2 [∵a 2 =3b 2 ] \Rightarrow \quad { b }^{ 2 }={ 3c }^{ 2 }⇒b 2 =3c 2
\Rightarrow \quad 3|{ b }^{ 2 }\quad \quad \left[ \because 3|3{ c }^{ 2 } \right]⇒3∣b 2 [∵3∣3c 2 ] \Rightarrow \quad 3|b\quad \quad ...\left( ii \right)⇒3∣b...(ii) From (i)(i) and (ii),(ii), we observe that aa and bb have at least 33 as a common factor. But, this contradicts the FACT that aa and bb are co-prime. This MEANS that our assumption is not correct. Hence, \sqrt {3} 3 is an irrational number. |

Ifcosecx+cotx =k then prove that cos x=k²-1/k²+1 |
Answer» Solution :-cosec x + cot x = k ⇒ cot x = k - cosec x Squaring on both sides ⇒ cot² x = (k - cosec x)² ⇒ cot² x = k² + cosec² x - 2k. cosec x ⇒ 2k. cosec x = k² + cosec² x - cot² x ⇒ 2k. cosec x = k² + 1 [ Because cosec² x - cot² x = 1 ] ⇒ cosec x = (k² + 1)/2k = Hypotenuse/OPPOSITE side
By PYTHAGORAS theorem ⇒ (ADJACENT side)² + (Opposite side)² = (Hypotenuse)² ⇒ (Adjacent side) ² = (Hypotenuse)² - (Opposite side) ² ⇒ (Adjacent side)² = (k² + 1)² - (2k) ² ⇒ (Adjacent side)² = (k²)² + 1² + 2k² - 4k² ⇒ (Adjacent side)² = (k²)² + 1² - 2(k²)(1) ⇒ (Adjacent side)² = (k² - 1)² ⇒ Adjacent side = k² - 1 cos x = Adjacent side /Hypotenuse = (k² - 1)/(k² + 1) Hence proved |
