球坐标系中,计算sin2θ时,采用的是如下公式,感觉不理解为什么要搞一个max函数,直接1 - cosTheta(w) * cosTheta(w)不行吗,另外,即使要用max,max的第一个参数应该是T(0)的平方吧 //计算sin(theta)的平方template<typename T>inline T sinTheta2(constVec3<T> &w) {returnstd::max(T(0),1- cosThe...

Determine the maximum value and the minimum value of f (x, y) = x^2 + y^2 - x - y on the closed unit disk D: x^2 + y^2 less than or equal to 1. (Hint: Recall that the unit circle x^2 + y^2 = 1 can be parametrized as x = cos t, ...
