8(cos(π2)+isin(π2))8(cos(π2)+isin(π2)) 使用公式r=√a2+b2r=a2+b2计算从(a,b)(a,b)到原点的距离。 r=√(8cos(π2))2+(sin(π2)⋅8)2r=(8cos(π2))2+(sin(π2)⋅8)2 化简√(8cos(π2))2+(sin(π2)⋅8)2(8cos(π2))2+(sin(π2)⋅8)2。
func vvcosisin(OpaquePointer, UnsafePointer<Double>, UnsafePointer<Int32>) Calculates the cosine and sine of each element in an array of double-precision values. func vvcosisinf(OpaquePointer, UnsafePointer<Float>, UnsafePointer<Int32>) Calculates the cosine and sine of each element in an arra...
这个是棣莫弗定理：先引入欧拉公式：e^ix = cosx + isinx 将e^t,sint ,cost 分别展开为泰勒级数：e^t = 1 + t + t^2/2!+ t^3/3!+ …… + t^n/n!+ …… sint = t - t^3/3!+t^5/5!-t^7/7!+……-…… cost = 1 - t^2/2!+t^4/4!-t^6/6!+……-…… ...
