Given sec tetha is equal to 13/12 calculate all other trigonometric ratios. |
|
Answer» This is the step wise answer-First draw a right triangleGiven,sec theta=13/12.So,sec theta=h/bHence,h=13 and b=12Now finding p by Pythagoras theorem we get p=5Now,Sin theta=p/h=5/13Cos theta=b/h=12/13Tan theta=p/b=5/12Cot theta=b/p=12/5Cosec theta=h/p=13/5. Sin theta=5/13 , cos theta=12/13 , tan theta=5/12 , cosec theta=13/5 , cot theta= 12/5 Sec theeta =13/12 , Cos theeta =12/13 , Sin theeta =5/13 , Cosec theeta =13/5 , Tan theeta =5/12 , Cot theeta =12/5 Sec theta =13/12 means hypotenuse=13 nd base 12 by Pythagoras theorem perpendicular 5 and we can calculate other ratios |

Solution of a quadratic eqn by completing the square. How to find it |
| Answer» We have, 2x2 + x + 4 = 0Dividing both sides by 2, we get{tex}x^2 +{1 \\over 2}x + 2 = 0 {/tex}{tex}\\implies (x)^2 + {1 \\over 2}x + {1 \\over 16} = -2 + {1 \\over 16}{/tex}{tex}\\implies (x)^2 + 2(x) ({1 \\over 4})+ ({1 \\over4})^2= {- 32 +1 \\over 16}{/tex}{tex}\\implies (x + {1 \\over4})^2 = -{31 \\over 16} <0{/tex}Which is not possible, as square cannot be negative.So, there is no real value of x which satisfy the given equation.Therefore, the given equation has no real roots. | |

Find the value of k for which a system equation 3x+y=1 and (2k-1)x+(k-1)y=2k+1 |
| Answer» The given pair of linear equation is3x + y = 1, (2k - 1) x + (k - 1) y = 2k + 1{tex}\\Rightarrow{/tex} 3x + y - 1 = 0Here, (2k - 1)x + (k - 1) y - (2k + 1) = 0a1 = 3, b1 = 1, c1 = -1a2 = 2k - 1, b2 = k - 1, c2 = -(2k + 1)for having no solution, we must have {tex}\\frac{{{a_1}}}{{{a_2}}} = \\frac{{{b_1}}}{{{b_2}}} \\ne \\frac{{{c_1}}}{{{c_2}}}{/tex}{tex}\\Rightarrow \\frac{3}{{2k - 1}} = \\frac{1}{{k - 1}} \\ne \\frac{{ - 1}}{{ - (2k + 1)}}{/tex}From above we have\xa0{tex}\\frac{3}{{2k - 1}} = \\frac{1}{{k - 1}}{/tex}{tex}\\Rightarrow{/tex} 3(k - 1) = 2k - 1{tex}\\Rightarrow{/tex} 3k - 3 = 2k - 1{tex}\\Rightarrow{/tex} 3k - 2k = 3 - 1{tex}\\Rightarrow{/tex} k = 2Hence, the required value of k is 2. | |
