a > 0 {\displaystyle a>0} These identities can be used to derive the product-to-sum identities. By setting θ=2x{\displaystyle \theta =2x}and t=tan⁡x,{\displaystyle t=\tan x,}this allows expressing all trigonometric functions of θ{\displaystyle \theta }as a rational fractionof t=tan⁡θ2{\textstyle t=\tan {\frac {\theta }{2}}}: sin⁡θ=2t1+t2,cos⁡θ=1−t21+t2,tan⁡θ=2t1−t2. 2009-06-13 · This Site Might Help You.
