Exponents and logarithms, multiple pages
Exponents and logarithms, multiple pages This is part of our refreshers since these functions are widely used everywhere. We will just stick to the properties and teach the students how to solve this type of […]
DIVISIBILITY
DIVISIBILITY When solving complex problems, we can encounter a situation where we want to know if a large number is divisible by our regular digits. In higher level courses in this site, we may use […]
Spherical trigonometry
Spherical trigonometry The spherical trigonometry is the branch of spherical geometry which deals with spherical triangles defined by great circles on the sphere. It allows us to calculate the trigonometric functions of the sides and […]
Fonctions trigonométriques élémentaires
Fonctions trigonométriques élémentaires Après l’introduction des trois fonctions trigonométriques (Sinus, cosinus et tangente) d’un angle , nous allons introduire leurs inverses à ne pas confondre avec les fonctions inverses. Sécante: C’est l’inverse de la fonction […]
