This precalculus video tutorial provides a basic introduction into the rational zero theorem. It explains how to find all the zeros of a polynomial function by using the rational zero theorem and by factoring polynomials. The rational zero theorem helps you to identify the first zero by listing all possible rational zeros and then evaluating the function to see if it's equal to zero at that particular value of x. This video also explains how to find all zeros of a polynomial function using synthetic division. You need to know how to factor trinomials and how to solve quadratic equations using the quadratic formula. This video contains plenty of examples and practice problems.

Hent materialet gratis her: https://anettekmatematik.com/o....vergangen-fra-plus-t

Overgangen fra plus til gange er det første værksted jeg bruger, når mine elever skal lære at gange tallene i den lille tabel.
I dette værksted bruger eleverne det de allerede kan fra plus og leger sig frem til en forståelse af sammenhængen mellem plus og gange.
Som altid er eleverne er glade for at lege og spille sig til ny viden, og det er et populært værksted at hente i min værkstedskasse.

There's an invisible force shaping our lives, affecting the weather, climate, land, economy, and just whether a flag looks majestic or not - we're talking about the wind! Today we’re going to go into the science of where the wind comes from and take a closer look at the major wind systems and pressure belts across the globe. We'll explain how the Coriolis effect causes the winds to curve (and makes air travel a bit more complicated), explore the doldrums and horse latitudes that could stall ships for days, and show the enormous impact the trade winds had on European colonization of the Americas.

In which John Green teaches you about the Great Depression. So, everybody knows that the Great Depression started with the stock market crash in 1929, right? Not exactly. The Depression happened after the stock market crash, but wasn't caused by the crash. John will teach you about how the depression started, what Herbert Hoover tried to do to fix it, and why those efforts failed.

On May 18th 1933, on the direct orders of Stalin himself, 5000 men and women arrived at Nazino, a small isolated island on the River Orb, deep in the remote and barren wilderness of Western Siberia. Within a matter of weeks, 4000 of them would either just die from exposure, disappear, drown or be eaten.
This was the real life Battle Royale.
