Johansson, B. Tomas – International Journal of Mathematical Education in Science and Technology, 2019
A method based on oblique projection is presented for construction of sundials. The derived formulas are classical, but usage of vectors and projections renders a coherent presentation rather than a number of special cases. The presented work is aimed to be useful for those taking a beginning module on vector algebra.
