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...
How do I find the sin of theta/2? To find the sin of theta/2: Write down the sine half-angle equation: sin(θ/2) = ±√[(1-cos(θ))/2]. Replace theta θ within the equation and solve the square root. To choose the sign, follow this rule: The result is positive (+) if...
Secondly, the proof of the square of sine formula is as follows: $$\sin^2\theta=\frac{1}{2}-\frac{1}{2}\cos2\theta$$。 $$\Rightarrow \sin^2\theta=\frac{1}{2}-\frac{1}{2}(\cos^2\theta-\sin^2\theta)$$。 $$\Rightarrow \sin^2\theta=\frac{1}{2}-\frac{1}{2}\co...

To prove the identity (1−sinθ+cosθ)2=2(1+cosθ)(1−sinθ), we will start with the left-hand side (LHS) and manipulate it to show that it equals the right-hand side (RHS). 1. Start with the LHS: (1−sinθ+cosθ)2 2. Expand the square using the identity (a+b+c...
This takes the sin and cos algorithms from Optimized Routines under MIT license, and converts them to Numpy intrinsics. The routines are within the ULP boundaries of other vectorised math routines (<4ULP). The routines reduce performance in some special
