Kepler's third law states that the square of the period of any planet is proportional to the cube of its orbital radius.To derive it, two equations are required: F=GMm/r^2 and F = mv^2/r. These are Newton...

First, if k=0 then the equation has no real roots since in this case we would have 5=0 (this is a proof by contradiction).
A quadratic equation of the form ax^2+bx+c=0 has no real roots if the discri...

The process of synaptic transmission is when electrical nerve impulses, known as action potentials, travel from the dendrites of the cell (the receptor site) to the axon terminal. When these action potent...

Lorsque j'ai du temps libre, j'aime lire des romans d'aventures, me promener dans la nature ou bien cuisiner des desserts! En effet, je prépare souvent des gâteaux avec ma mère: elle me montre ce qu'il fa...

Say you have the term y=3X² . You start by bringing the power down and placing it in front of the 3 so they multiply like so y=2x3X² then next you take one away from the power like s...
