eelooo Posted December 28, 2017 Report Share Posted December 28, 2017 (edited) Hello, I have been really struggling to find an IA topic I am in math sl . My teacher tries to be helpful but he is an extremely busy man, I really want to do something on Sundials such as how sundials are made, I just don't know if this is a good IA topic I am very lost I know I want to do something with sundials but don't know exactly what. Maybe I could do something with the equation of time? Edited December 28, 2017 by eelooo Reply Link to post Share on other sites More sharing options...
Light77 Posted December 29, 2017 Report Share Posted December 29, 2017 How about analyzing the change of the angle of the shadow relative to some axis as time changes? This could initiate some interesting mathematical concepts, possibly in the areas of trigonometry and vectors. 1 Reply Link to post Share on other sites More sharing options...
eelooo Posted December 29, 2017 Author Report Share Posted December 29, 2017 thank you so much for replying trig and vectors are definitely my stronger areas of math I was just scared that the topic wasn't good enough for a good grade on my ia since my teacher has not made any comments on it.
