10 Secret Trig Functions Your Math Teachers Never Taught You...(because they are from a pre-calculator world) A diagram with a unit circle and more trig functions than you can shake a stick at. (It's well known that you can shake a stick at a maximum of 8 trig functions.) The familiar sine, cosine, and tangent are in blue, red, and, well, tan, respectively. The versine is in green, and the exsecant is in pink. Excosecant and coversine are also in the image.

- this was a future planning hack I created in March which I've called the calendar wheel. I was inspired by something similar I found on the Moleskine website a few years back and wanted to give it my spin. I love mind mapping and my brain functions visually so this was something I toyed with and worked well. I basically wrote down all events, appointments, birthdays and connected them to the corresponding date/day on the wheel. Thinking of doing again for July and possibly selling some…
