The adjacent side (\(a\)) is next to the angle in question (\(x\)). The trigonometric ratios for the angles 30°, 45° and 60° can be calculated using two special triangles. An equilateral ...
For one, trigonometry becomes a lot easier. Instead of memorizing several complicated trig formulas, you need only one equation to rule them all: Euler’s 1740 formula. With decent algebra skills ...
