4. Half-Angle Formulas by M. Bourne We will develop formulas for the sine, cosine and tangent of a half angle. Half Angle Formula - Sine We start with the formula for the cosine of a double angle that we met in the last section. cos 2θ = 1− 2sin2 θ Now, if we let θ...
Half-angle formulas extend our vocabulary of the common trig functions. After reviewing some fundamental math ideas, this lesson uses theorems to...
Notice that some half-angle formulas have both a positive and a negative version. When deciding which one to use, consider which quadrantθ2is in, and remember in whichquadrantssin, cos, and tan are positive or negative, per the quadrant rule. ...
Use half-angle formulas to find exact values. Figure 1. Bicycle ramps for advanced riders have a steeper incline than those designed for novices. Bicycle ramps made for competition (see (Figure)) must vary in height depending on the skill level of the competitors. For advanced competitors...

The purpose of this short note is to show that the familiar half-angle formulas sin~2x =(1-cos2x)/2 and cos~2x = (1+cos2x)/2(1) have the neat generalisations to complex numbers |sin~2(x+y)=(cosh 2y -cos2x)/2 and |cos~2(x + iy)|=(cosh 2y + cos2x)/2.MARCUS WRIGHT...
