Techniques of integration
If the primitive function of an integrand can be found it is always best to take advantage of the fundamental theorem of calculus. In order to be able to determine integrals whose indefinte integrals(primitive functions) cannot be found immediately some … Fortsätt läsa
Venn-diagrams
A good way of illustrating probabilities is to use so-called Venn-diagrams. In effect this means representing the probability of an event with circles. Mutually excluding events can be represented by two separate non-overlapping ciecles. P(A) + P(B) = P(A U … Fortsätt läsa
Diophantine equations
A Diophantine equation is an equation in which only integers are allowed as coefficients. Also the solutions must be integers. This can be written as ax + by = c. This is a linear diophantine equation. For non-linar diophantine equations … Fortsätt läsa

Probability
The probability of a certan outcome of an experiment can be calculated as the quotient of the number of outcomes giving the desired result and the number of possible outcomes. P(A) = (number of outcomes giving the desired results)/ (number … Fortsätt läsa

Regula de tri och ekvationer samt olikheter
Ekvationelösningens grunder visas i denna filmsnutt. This is one of the most useful methods in mathematics when it comes to usefulness. It means ‘the rule of three’ and concerns computing the third un-known variable when the two others … Fortsätt läsa
