Consider equation (x - sin alpha) (x-cos alpha) - 2 = 0 . Which of the followingis /are true? |
|
Answer» If `0lt alpha LT (pi)/(4)`, then the equationhas both ROOTS in `(sin alpha, cos alpha)` Then. ` f(sin alpha) = - 2 lt 0 ` and ` f(cos alpha) = - 2 lt 0 ` and ` f(cos alpha ) = - 2 lt 0 ` So, sin ` ALPHAAND cos alpha ` lie between the roots
