Find cosec30 and cos60 geometrically. Any idea? |
|
Answer» We can do it by drawing an equilateral triangle and then drawing a median..... Take the side of equi triangle a and then find length of median by pythagoras theorem and then as we know equi triangle has 60 angle so by taking help of trigonometric ratios we can further find it U can find it by drawing a equilateral triangle draw a perpendicular now we know that opposite side divided into equal .. Now find cosec 30 and cos60 cosec30 is 2 and cos60 is 0.5 |

1 is a zero of 7x-x3-6 polynomial find other zero |
| Answer» The given polynomial is -x3 + 7x - 6 and let\xa0f (x) = -x3 + 7x - 6 .Since 1 is a zero of f(x), so (x - 1) is a factor of f(x).Now we divide f(x) = -x3 + 7x - 6\xa0by (x - 1), we obtain\xa0Where quotient =\xa0(-x2\xa0- x + 6){tex}\\therefore{/tex}\xa0f(x) = (-x3\xa0+ 7x -\xa06) = (x - 1)(-x2\xa0- x + 6){tex}= - ( x - 1 ) \\left( x ^ { 2 } + x - 6 \\right) = - ( x - 1 ) \\left( x ^ { 2 } + 3 x - 2 x - 6 \\right){/tex}{tex}= ( 1 - x ) [ x ( x + 3 ) - 2 ( x + 3 ) ] = ( 1 - x ) ( x + 3 ) ( x - 2 ){/tex}{tex}\\therefore{/tex}\xa0f(x) = 0 {tex}\\Rightarrow{/tex}\xa0{tex}( 1 - x ) ( x + 3 ) ( x - 2 ){/tex} = 0{tex}\\Rightarrow{/tex}\xa0(1 - x ) = 0 or (x + 3) = 0 or (x - 2) = 0{tex}\\Rightarrow{/tex}\xa0x =\xa01 or x = -3 or x = 2.Thus, the other zeros are -3 and 2 | |
