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...

We derivean useful formula for the sensitivity which depends only two parameterssigma_db/\\sqrt{n} (the uncorrelated bin-to-bin systematic error over thesquare-root of the number of bins) and sigma_dB (the bin-to-bin correlateddetector specific systematic error)....
Note that you draw a square with diagonal d = 1. The horizontal and vertical sides of the squares are, respectively, the cosine and the sine of the angle 45°. To calculate them, use the formula for the diagonal of a court: d = l ·√2. Find the sine: sin(45°) = 1/√2 =...
±1−CosA2 If A/2 is in the first or second quadrants, the formula uses the positive sign. If A/2 is in the third or fourth quadrants, the formula uses the negative sign Cos A2 = ±1+CosA2 If A/2 is in the first or fourth quadrants, the formula uses the positive sign. ...
The sine function of an angle is equal to the opposing side's length divided by the hypotenuse side's length, and the formula is as follows: \[sin\theta =\frac{\textrm{opposite side}}{\textrm{hypotenuse side}}\] The sides of a triangle are proportional to the sine of the opposite an...

Now, square both sides to find sin2θ:sin2θ=cos4θ Step 4: Expressing sin2θ in Terms of cos2θWe can also write:1−cos2θ=cos4θRearranging gives:cos4θ+cos2θ−1=0 Step 5: Cubing Both SidesNow, cube both sides of the equation cos4θ+cos2θ=1:(cos4θ+cos2θ)3=13...
