由于 ( \tan(\theta) = \frac{\sin(\theta)}{\cos(\theta)} )，我们可以将上述恒等式转换为涉及tan的形式：1+tan2(θ)=cos2(θ)1 因此，如果我们知道了tan的值，我们可以通过以下公式计算cos的值：cos(θ)=1+tan2(θ)1 同样，如果我们知道了cos的值，我们可以计算tan的值：tan(θ)=cos2(θ)1...
Now, we can express this in terms of tangent:=1−tan(θ2)1+tan(θ2)Using the tangent subtraction formula:tan(π4−x)=1−tanx1+tanxwe can identify that:1−tan(θ2)1+tan(θ2)=tan(π4−θ2) ConclusionThus, we have proved that:cosθ1+sinθ=tan(π4−θ2)Hence, the ...

The Fourier-cosine expansion (COS) method is used to price European options numerically in a very efficient way. To apply the COS method, one has to specify two parameters: a truncation range for the density of the log-returns and a number of terms N to approximate the truncated density by...
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 ...
