-pi*0.11*0.11*480000*(0.14*0.09./(0.14*0.09+0.045*1.05-0.045*cos(x)-0.045*0.05*cos(2*x))).^1.2=-101000*pi*0.11*0.11怎么解出x?

答案

x=solve('-pi*0.11*0.11*480000*(0.14*0.09/(0.14*0.09+0.045*1.05-0.045*cos(x)-0.045*0.05*cos(2*x)))^1.2=-101000*pi*0.11*0.11')就可以了得出两个实数解x =1.2217096986774274046650233415025-1.221709698677427...
