What is the correct tense for essays related to mathematics?
I was told by a student from China that all mathematics essays should be written in present tense. However, some tense usages are looks truly strange to me. Here are some examples:

The propagation characteristic of non-isospectral variable coefficient Korteweg-de Vries (vcKdV) equation is analyzed. The one-solitonic solution and two-solitonic solution of normal KdV equation are obtained by the bilinear method, and the propagation characteristics of this equation are also displayed in this paper.

And the OIW is simulated and analyzed by that calculation formula.

Answer

I'm not a mathematician, but I used to teach college writing. Usually, if you're writing this for college, or for a journal, you use the format that the professor, or the journal, asks for. Some prefer everything in present tense. Grammatically, there's no reason you couldn't use any tense. But, again, it's always best to ask the audience you're writing for what type of format they want.
