当我们更新了三角函数的定义方式后,自然就会遇到三种函数的值的相互关系,比如已知$\sin\theta+\cos\theta$[四则运算之一,加法]的值,如何求解关于$\sin\theta$和$\cos\theta$之间的四则运算的剩余运算[减法、乘法、除法],是本博文探讨的重点。
Convert from sin(θ)cos(θ)sin(θ)cos(θ) to tan(θ)tan(θ). 1=tan(θ)1=tan(θ)Rewrite the equation as tan(θ)=1tan(θ)=1. tan(θ)=1tan(θ)=1Take the inverse tangent of both sides of the equation to extract θθ from inside the tangent. θ=arctan(1)θ=arctan(1)...
