Precalculus: Trigonometric Functions - SparkNotes

WebThis video shows how to use Descartes rule of signs to determine the number of possible positive and negative zeros. Remember that this comes from looking a... WebUse Descartes' Rule of Signs to find the number of real roots of:f (x) = x5 + 4x4 − 3x2 + x − 6. First, I look at the positive-root case, which is looking at f (x): f ( x) = +x5 + 4 x4 − 3 x2 + x − 6. The signs flip three times, so there are three positive roots, or one positive root. Either way, I definitely have at least one positive ... fishman football pool
