# Sierpinski Triangle in Fortran 95

I was assigned the task of writing a program (code) in Fortran (.f95) that would plot points according to X and Y and form a figure that resembled the Sierpinksi Triangle. For those of you who are not aware of what the Sierpinksi triangle is,I will give a brief description, but a quick web search…

# How To Learn

Brainstorming: The key to understanding something is to know the what, why, how, where, when of a subject. Fast learners do these connections automatically to some extent. You can artificially improve it by using techniques like mind-mapping. Muscle memory: A lot of topics need muscle memory. If you can know multiplication tables, physics constants, some…
