welcome back! six weeks to go until the next break ;)

**ib math sl grade 11**
we'll have another look at functions this week. the more we look at it, the more we shall understand! this time it's about which changes in a function modifies which parts of it.** **a little repeat from last years graph transformations. this should be finished within the week, and a mini-test should pop up next tuesday, january 18. the hw quiz on friday will focus on 5 B1, B2 and B3.

**ib math sl grade 12**

it's on to more differentiation; logarithmic, exponential and trigonometric derivatives are still unknown to us; you might want to have a general look at chapters 19 and 20, parallel to the classes. on thursday and friday next week, we'll allocate time to prepare for the mocks. the hw quiz on friday will have a question each from 19 A, B and C.

** ib physics grade 11**

wave phenomena is on our menu. we'll do this topic differently: i will find us some time today for research, since i'll have each one of you presenting a subtopic in topic eleven of the syllabus. standing waves will be presented by chris, the doppler effect by tim, diffraction by nino, resolution by yana and sara, and polarization by daniel and dennis. all of these will exclude exercises (only examples are desired).

hi you four. we'll split up topic 8, a perfect review topic, to be presented creatively. we'll take some time for research and preperation tomorrow (no great physicist presentation)**, **as follows: aidin will take over energy degradation and power generation, max will do world energy sources, promita will present fossil fuel power production, and bilal shall be** **our expert on the greenhouse effect. we'll do the other topics together; follow the syllabus outline (which can be found as a link on this page), and make sure everything is covored.
