Cos4t+sin6t傅里叶级数
WebJul 21, 2024 · Explanation: Let, I = ∫cos4t ⋅ sin2tdt. Observe that, cos and sin both have even Power. So, we have. to convert them into Multiple Angles, using the Identities, (1):cos2θ = 1 + cos2θ 2,(2):sin2θ = 1 − cos2θ 2, (3):2cosαcosβ = cos(α+ β) +cos(α− β). Now, cos4t ⋅ sin2t = 1 4(4cos2t ⋅ sin2t)(cos2t), Web这个公式与我们上述定义的傅里叶级数分析公式只有常数倍数上的一点差异(目前我还没有找到特别合理的数学解释的原因，我个人认为无关紧要，因为如果是复指数形式的傅里叶 …

WebNote that the three identities above all involve squaring and the number 1.You can see the Pythagorean-Thereom relationship clearly if you consider the unit circle, where the angle is t, the "opposite" side is sin(t) = y, the "adjacent" side is cos(t) = x, and the hypotenuse is 1.. We have additional identities related to the functional status of the trig ratios:
