WebJul 1, 2024 · Locate and remember the 6 basic trig functions of π/4, which is a special angle. Here’s another special angle for you to remember. For this one, you’ll use the ratios for a 45-45-90 triangle. It has sides of 1 and a hypotenuse of √2. So if plotted on a unit circle, the basic trig functions are: sinπ/4 equals 1/(√2) cosπ/4 equals 1/(√2) WebTitle: Introduction to right triangle trigonometry 1.

Imagine a pizza cut into 360 equal pieces (what a mess). Each little slice represents one degree. The first quadrant is the upper right-hand corner of the coordinate plane. That first quadrant is 1/4 of the entire plane. So, if a full circle with its center at the origin has a total of 360 ... biohacking conference 2020
