The website is a blessing. I'm so happy to have stumbled upon it and I recommend it to anyone who is preparing for the SL math exam. The videos have been so successful in helping me recall content from the years...

The site is great for revising the basic understandings of each topic quickly. Especially since you are able to test yourself at the end of each page and easily see where you need to improve.

It has really a lot of tips to prepare IB students for the exams, as well as exercises and guidance. It gives a clear outline of all knowledge we need to complete them appropriately.
Integration by parts is a method of integration that we use to integrate the product (usually !) of two functions. The aim is to change this product into another one that is easier to integrate. Although the formula looks quite odd at first glance, the tec
Integration by substitution or U-substitution is a method that will help you integrate many different functions. By changing the variable of the integrand, we can make an apparently difficult problem into a much simpler one. The challenge is recognising wh
Integration is sometimes called antidifferentiation, as it is the opposite process of differentiation. When we find an indefinite integral we find a function with an abritrary constant, C. When we find a definite integral, we find a numerical value.
Implicit Equations are often used to represent relations that cannot be expressed as functions (one to many relations or many to many relations). These often have really interesting graphs. This page will allow to explore some of these graphs and consider
Logarithms are useful for solving problems involving indices (or exponents). In fact, logarithms are just indices in disguise! The definition of a logarithm helps you to see its equivalence with indices
