什么是1 1/4 * 2 2/3?
10/3 1 1/4 = 5/4 2 2/3 = 8/3所以我们有:5/4 * 8/3 = 40/12 = 10/3
什么是1/3百分比形式?
1/3 = 33.33%只需将分数乘以100%即可将其转换为百分比形式。三分之一= 1/3 * 100%= 33.33%
什么是1 = e ^ y-xcos(xy)的隐式导数?
(dy)/ dx =(cosxy-xysinxy)/(e ^ y + x ^ 2(sinxy))1 = e ^ y-xcos(xy)rArr(d1)/ dx = d / dx(e ^ y-xcos) (xy))rArr0 =(de ^ y)/ dx-(d(xcos(xy)))/ dx rArr0 =(dy / dx)e ^ y - (((dx)/ dx)cosxy + x(dcosxy) / dx)rArr0 =(dy / dx)e ^ y-(cosxy + x(dxy)/ dx(-sinxy))rArr0 =(dy / dx)e ^ y-(cosxy + x((y + x(dy) )/ dx)( - sinxy)))rArr0 =(dy / dx)e ^ y-(cosxy + x(-ysinxy-x(dy)/ dx(sinxy)))rArr0 =(dy / dx)e ^ y - (cosxy-xysinxy-x ^ 2(dy)/ dx(sinxy))rArr0 =(dy / dx)e ^ y-cosxy + xysinxy + x ^ 2(dy)/ dx(sinxy)rArr0 =(dy / dx )e ^ y + x ^ 2(dy)/ dx(sinxy)-cosxy + xysinxy rArr0 =(dy / dx)(e ^ y + x ^ 2(sinxy)) - cosxy + xysinxy rArrcosxy-xysinxy =
