please explain in detail the wavy curve method....im not that good at maths so need a detailed explanation....
If you have a polynomial function like (ax+b)(cx+d)....... ,and would like to know where the function is +ve or -ve( on the real line of course) just arrange the roots in ascending order as on the no line.Start from the rightmost root.All values of the function for x greater than this root are +ve.Then in the interval between the largest and second largest the value is -ve and its goes on alternating between the roots. As an example , take the case of x(3x+1)(3x-1),The roots are -1/3,0,1/3.x > 1/3 => expression +ve0< x < 1/3 => -ve-1/3< x < 0 =>+vex<-1/3 => -veSounds familiar ?Its called wavy curve because you can draw something of a wiggling worm on the no line.
