Posted October 26, 2014 Hi! I'm currently working on my Math IA (HL), in which I'll be using differential equations. Now, do I have to explain what a derivative is? As in, the gradient of a line as x --> 0 using limits? This should be in the SL syllabus, right? I don't want to include unnecessary stuff ...Thanks for your amazing advice!

Posted October 26, 2014 Hi! According to my teacher, you need to explain things if its not in the syllabus so i guess you don't need to explain what a derivative is ^^ 1 person likes this Share this post Link to post Share on other sites

As sushichan said, you don't need to! Also, you can structure your IA in any way you like; just mention your scope of investigation before you begin your writing. For example, i did mine on inhomogeneous second-order linear differential equations. However, to fully understand the inhomogeneous equations, i also needed to investigate about the homogeneous cases; and I soon realized that this is too broad. So in the beginning, I assumed that the people who read my IA knew everything about the homogeneous DE. By assuming this, i would avoid having to include the unnecessary information about the homogenous case. I realized that the syllabus change in math last year leaves quite a lot of room for students to think more freely. So feel free to write it the way you like! Good luck 3 people like this Share this post Link to post Share on other sites
