三角叠加公式也叫做辅助角公式,它不仅可以处理三角函数问题.而且适当地变换、合理转化后,它在解决许多非三角问题中仍能发挥重要作用.三角迭加公式:对于正弦与余弦的叠加函数asinx+bcosx,存在终边通过点(a,b)的角φ∈[0,2π),使得 The triangular superposition formula is also called the auxiliary angle formula. It not only can deal with the trigonometric function problem, but it can still play an important role in solving many non-triangular problems after proper transformation and reasonable transformation. Triangle addition formula: For sine and cosine The superposition function asinx+bcosx has the angle φ∈[0, 2π) of the terminal edge passing point (a,b), making
