Since both sides are equal, the proof is now Odd/Even Identities. sin (–x) = –sin x cos (–x) = cos x tan (–x) = –tan x csc (–x) = –csc x sec (–x) = sec x cot (–x) = –cot x cos(x)sin(x) + sin(x)cos(x) Which is the double angle formula of the sine cos(x)sin(x) + sin(x)cos(x) = sin(2x) But since we multiplied by 2 early on to get to that, we need to divide by two to make the equality, so [math]\begin{align*} \sin x\cos x &=\left(\frac{e^{ix}-e^{-ix}}{2i}\right)\left(\frac{e^{ix}+e^{-ix}}2\right)\\ &=\frac{(e^{ix}-e^{-ix})(e^{ix}+e^{-ix})}{4i}\\ & Joshua Siktar's files Mathematics Trigonometry Proofs of Trigonometric Identities Statement: $$\sin(2x) = 2\sin(x)\cos(x)$$ Proof: The Angle Addition Formula for sine can be used: Basic trigonometric identities Common angles Degrees 0 30 45 60 90 Radians 0 ˇ 6 ˇ 4 ˇ 3 ˇ 2 sin 0 1 2 p 2 2 p 3 2 1 cos 1 p 3 2 p 2 2 1 2 0 tan 0 p 3 3 1 p 3 Reciprocal functions cotx= 1 tanx cscx= 1 sinx secx= 1 cosx Even/odd sin( x) = sinx cos( x) = cosx tan( x) = tanx Pythagorean identities sin2 x+cos2 x= 1 1+tan2 x= sec2 x 1+cot2 x Free math lessons and math homework help from basic math to algebra, geometry and beyond. Students, teachers, parents, and everyone can find solutions to their math problems instantly. equation will be converted into terms of sinx and cosx. According to one of the reciprocal identities, secx = 1 cosx. sinx 1 • 1 cosx =tanx When multiplying across the top and the bottom, the result is sinx cosx.

and, which can be factored as (sin x + cos x)(sin x + cos x) so, going back to the original equation, you have (sin x + cos x)(sin x + cos x)/(sin x + cos x) and since "(sin x + cos x)" is common factor in both the numerator and the denominator, it will simply cancel out and you are the only left with Answer to Complete the identity.
