The sum identities of sine, cosine, and tangent provide a way to prove how the double angle formulas work. When an angle is doubled or multiplied by 2, this is the same as adding the angle to itself. The identities use the Greek letters α and β to represent unknown angles. We can...

The total force Fy must be equal to the sum of both axle side forces. Each axle experiences a slip angle equal to β, because the yaw rate r=0. Consequently, Fy=Fy1(β)+Fy2(β) which can be described, for linear axle characteristics, as Fy=Yβ·β=−(Cα1+Cα2)·β The ...
