WebPythagoras. Pythagoras' Theorem says that for a right angled triangle, the square of the long side equals the sum of the squares of the other two sides:. x 2 + y 2 = 1 2. But 1 2 is just 1, so:. x 2 + y 2 = 1 equation of the unit circle. Also, since x=cos and y=sin, we get: (cos(θ)) 2 + (sin(θ)) 2 = 1 a useful "identity" Important Angles: 30°, 45° and 60°. You … WebEasy as that. If the angle is unknown, but the lengths of the opposite and adjacent side in a right-angled triangle are known, then the tangent can be calculated from these two measurements. For example, if a = 15 and b = …
