偏导数的问题,还有用余弦公式A plane flying with a constant speed of km/min passes over a ground radar station at an altitude of km and climbs at an angle of degrees.At what rate,in km/min is the distance from the plane to the radar statio 导数的计算练习题M=100Q^2,求dQ/dM,用M表示.要求有推导过程,还有用了哪些导数公式? 正,余弦的公式 两角差的余弦公式 余弦定理的公式 偏导数公式上的一个问题?这个公式中 若 ξ=X 这个公式怎么看都不成立 怎么回事? （a)的导数.公式忘记了 余弦的正弦次幂的导数 X的余弦值 的导数 是多少 对数导数公式中x=1还成立吗(loga X)'=1/Xlna 中的条件是a>0,a≠1,X>0,可当X=1时,loga 1=0,0的导数是0,可这时用公式1/Xlna==1/lna≠0请解释哪里有问题? 求大神解答一级建造师《工程经济》的问题!老师说该题中选用的公式为C1 =CF1+CU1Q但书上说当方案的有用成果不相同时C1 =CF1+CU1Q,但是选项A/B/C/D中每一个选项中有用成果都是一样的常量,为何还 正弦余弦函数的导数怎么求 为什么正弦的导数是余弦? 怎么求反正,余弦函数的导数 余弦函数平方分之一的导数是什么? 关于偏导数的问题! 求偏导数的问题 导数方面的知识需要函数的导数公式(对数,指数,正弦,余弦)以及导数运算法则的推导,需要详细过程(过程内最好不要用到别的导数公式)
