9.3: Double-Angle, Half-Angle, and Reduction Formulas
WebDouble angle identities are trigonometric identities that are used when we have a trigonometric function that has an input that is equal to twice a given angle. For example, we can use these identities to solve \sin (2\theta) sin(2θ). In this way, if we have the value of θ and we have to find \sin (2 \theta) sin(2θ), we can use this identity ... WebThese notes cover the double and half-angle trig formulas. Notes and one worksheet are included in this resource. The topics covered in this lesson include: Double and Half-Angle formulas for sine, cosine, and tangent using values on the unit circle Double and Half-Angle formulas for sine, cosine, and tangent using values NOT on the unit circle Two different … WebUse Reduction Formulas to Simplify an Expression. The double-angle formulas can be used to derive the reduction formulas, which are formulas we can use to reduce the power of a given expression involving even powers of sine or cosine.They allow us to rewrite the even powers of sine or cosine in terms of the first power of cosine. lsu cheerleaders 1981
