**IB HL Calculus Option Videos**

For those students studying the IB Maths Higher Level Calculus option, I’ve just finished putting together video playlists to cover the whole option syllabus. These include both videos teaching the course content and also worked past paper solutions. Hopefully this should make what is a demanding unit a little bit more manageable.

**Calculus Option Part 1:**

Limits, limits at infinity, determining if limits exist, differentiating from first principles, L’Hopital’s Rule, Squeeze theorem, Rolle’s theorem, Mean Value theorem.

**Calculus Option Part 2:**

differential equations, solving differential equations through separating variables, substitution and integrating factor, sketching slope fields.

**Calculus Option Part 3:**

Improper integrals, Comparison test, Riemann sums, divergence test, comparison test, limit comparison test, alternating series test, absolute convergence, power series, Ratio test.

**Calculus Option Part 4:**

Power series, Taylor and Maclaurin series,

**Other playlists**

You can find all the playlists for the:

HL core maths content here.

SL maths here

Studies maths here.

One of the main benefits of flipping the classroom is allowing IB maths students to self-teach IB content. There are currently a good number of videos on youtube which allow students to self teach syllabus content, but no real opportunity to watch videos going through IB Higher Level past paper questions. So, I’ve started to put some of these together:

**Playlist, Worked Exam Solutions:**

The videos above are all around 10 minutes long and consist of talking through the solutions to 2-3 IB HL maths questions. The best way to use these videos is to pause the video at the start of the question, attempt it, then watch the video to check the answer and make notes on the method. Click on the top left hand corner to change the video being shown in the playlist.

The playlists below combine these worked solutions with the syllabus content videos, all grouped into the relevant syllabus strands:

**Playlist 1, Algebra 1: **

Sequences, Binomial, Logs, Induction, Permutations, Gaussian elimination:

**Playlist 2, Complex numbers: **

Converting from Cartesian to Polar, De Moivre’s Theorem, Roots of Unity:

**Playlist 3: Functions: **

Sketching graphs, Finding Inverses, Factor and Remainder Theorem, Sketching 1/f(x), sketching absolute f(x), translating f(x):
