化简sin(theta)*cos(theta)*csc(theta) sin(θ)⋅cos(θ)⋅csc(θ)sin(θ)⋅cos(θ)⋅csc(θ) 将csc(θ)(θ)重写为正弦和余弦形式。 sin(θ)cos(θ)⋅1sin(θ)sin(θ)cos(θ)⋅1sin(θ) 约去sin(θ)sin(θ)的公因数。
The trigonometric angle identity sin(α+β)=sinαcosβ+cosαsinβsin(α+β)=sinαcosβ+cosαsinβ is exactly what you need. Note that A2+B2=C2A2+B2=C2, or (A/C)2+(B/C)2=1.(A/C)2+(B/C)2=1. Thus there exists an angle ϕϕ such that c...
