Let's use other trigonometric identities to calculate sin 2 theta in various ways. The first alternative formula uses: The Pythagorean identity: sin2(θ)+cos2(θ)=1sin2(θ)+cos2(θ)=1; and The formula for the square of a polynomial: (a+b)2=a2+b2+2ab(a+b)2=a2+b2+2ab...

The diagonal splits the square in two 45°45°-45°45°-90°90° right triangles. We can then find the length of the sides of such triangles, and the result will also be the sine of 45°45°: sin(45°)=2/2sin(45°)=2/2. Other interesting angles are 30°30° and 60°60...
