Hence origin does not lie in plane 2x y ≥ 8 So, we shade right side of line First we solve x 2y ≥ 10 Lets first draw graph of x 2y = 10 Put...
いろいろ 3x-y-2=0 2x y=8 181371-3x-y-2=0 2x+y=8 substitution method
0 The method to solve such differential equations is Substitute x 2 = u 2 x d x = d u and y 2 = v 2 y d y = d v Then it's neat, a dy/dx...
