用matlab求最大值i=(18-t^(2/3))-(5+t+2*t^(2/3))i是因变量,t是自变量.这个函数是减号，式子没化简，化简完是i=13-3*t^(2/3)-t

复数和三角函数问题sin(i*x+t)能不能表示成不含i的形式?其中i是虚数单位我本来的想法是先展开成sin(i*x)*cos(t)+cos(i*x)*sin(t)然后对其中含有i的两个三角函数用泰勒展开最后对数列求极限但是，

求助!有没有这个公式：定积分∫[Asin(2π/T)]^2=(A^2*T)/4高中物理交流电那块讲过,正弦式电流的有效值的√2倍就是电流的峰值.由此观之,令电流I=Asin(2π/T),可得(I有效)^2*T/2=∫I^2令sin(2π/T)=1,此

A又因为 I有效=I(max
