Prove that :tanθ+sinθ/tanθ-sinθ\u200b=secθ+1/secθ-1\u200b |
| Answer» (tanΘ + sinΘ)/(tanΘ - sinΘ)= [(sinΘ/cosΘ + sinΘ)] / [sinΘ/cosΘ - sinΘ]= sinΘ(1/cosΘ + 1) / sinΘ(1/cosΘ - 1)= sinΘ(secΘ + 1) / sinΘ)(secΘ - 1)= (secΘ + 1) / (sec Θ - 1)This is the only way the answer can be typed. Hope u understand. | |

Find a quadratic polynomial whose zeros are reciprocal of the zeros of polynomial P(x) = x2 – x - 6. |
|
Answer» Quadratic polynomial formed=x2+1/6x-1/6 Zeros of x2 -x -6=x2-3x+2x-6x= (X+2)(X -3)X= -2 or3So, it\'s reciprocal = -1/2and1/3.So, -1/2 +1/3= -1/6And, -1/2×1/3= -1/6Thus quadratic polynomial formed =x2+1/6x+1/6 6x2 +x -1 |

If x+1 is a factor of 2x3 + ax2 + 2bx + 1, then find the values of a and b given that2a—3b = (- 4 ) |
|
Answer» X + 1 is a factor of 2x3 + ax2 + 2bx + 1, so on substituting -1 in the polynomial we will get 0. On further calculation we get an equation: a - 2b = 1 - (1). Now we can find the value of a in terms of b and then substitute it in the equation given in the question: 2a - 3b = -4 - (2) . From here, we get b = -6 . Again substituting this value in the equation (1), we get the value of a to be - 11. This content has been hidden. One or more users have flagged this content as inappropriate.
