Maths SL IA Matrix Algebra

Recommended Posts

Hi, I came up with a topic “What type of function will produce the most accurate model of population growth in country X?” I made scatter plot using data about country’s population in given year. Now I want to use quadratic function to see how would it fit as a model and I’m wondering whether there is other way to find (a, b, c, and d for the equation y = ax3 + bx2 + cx + d) than applying matrix algebra (X = A-1 B) since matrix algebra is not a part of SL curriculum and I’m worried that using it may lower my mark.

No, matrix algebra is beyond SL so if you know what you are doing then going beyond the curriculum will only be beneficial.
