Find HCF of 81 and 237 and express it in linear combination of 81 and 237 |
| Answer» Since, 237 > 81On applying Euclid’s division algorithm, we get237 = 81 × 2 + 75 ...(i)81 = 75 × 1 + 6 ...(ii)75 = 6 × 12 + 3 ...(iii)6 = 3 × 2 + 0 ...(iv)Hence, and HCF (81, 237) = 3. 1 Write 3 in the form of 81x + 237y, move backwards3 = 75 – 6 × 12 [From (iii)]= 75 – (81 – 75 × 1) × 12 [Replace 6 from (ii)]= 75 – (81 × 12 – 75 × 1 × 12)= 75 – 81 × 12 + 75 × 12= 75 + 75 × 12 – 81 × 12= 75 ( 1 + 12) – 81 × 12= 75 × 13 – 81 × 12= 13(237 – 81 × 2) – 81 × 12 [Replace 75 from (i)]= 13 × 237 – 81 × 2 × 13 – 81 × 12= 237 × 13 – 81 (26 + 12)= 237 × 13 – 81 × 38= 81 × (– 38) + 237 × (13)= 81x + 237yHence, x = – 38 and y = 13 | |

Prove that (sin theta + Cosec theta)^2+(cos theta +sec theta)^2 = 7+ tan^2 theta + cot^2 theta |
|
Answer» LHS = (sin^2 theta + cosec^2 theta + 2×sin theta × cosec theta) + ( cos^2 theta + sec^2 theta + 2×cos theta × sec theta) => (sin^2 theta + cos^2 theta)+ cosec^2 theta + sec^2 theta + 2×sin theta×cosec theta + 2 ×cos theta × sec theta => 1 + (1+cot^2 theta) + (1+tan^theta) + (2×sin theta× 1/sin theta ) + ( 2× cos theta × 1/cos theta) => 7 + cot^2 theta + tan^2 theta... Now, LHS = RHS So, it\'s prove.... Wlcm..?muh kyu bana rkha h Thank you ? ?? Cosec ko sin.....and sec ko cos me change kar ke......do as given ...i mean perform their square....you definately get it,???? Used identity=> sin theta cosec theta=1, cos theta sec theta=1, sin^2theta+cos^2theta=1, cosec^2theta=1+cot^2theta. LHS= (sin theta+cosec theta)^2+(cos thetha+ sec thetha)^2(sin^2theta+coscec^2theta+2 sin theta cosec theta) + (cos^2theta+ sec^2theta+2cos theta sec theta) (sin^2theta+cosec^2theta+2) + (cos^2theta+sec^2theta+2) (sin^2theta+cos^2theta)+4+(cosec^2 thetha+sec^2theta) 1+4+(1+cot^2theta)+(1+tan^2 theta) = (7+tan^2theta+cot^2) Anybody here solve this ?? |
