Ask the big guy to do the next question, and the big guys will see how to do this question?

Boss, are you joking? What? The topics are all put up, you have nothing to do, I'll see you. Just kidding you. How old are you this year?

In order to solve this first-order linear differential equation, we need to first determine its type. According to the given square clear volt range xy'-2 y = 0, we can observe that it is a differential equation of separable variables. Rewrite the equation as:

y'(x) =2√y(x) /x

dy/√y = 2/x) dx

Now, the two sides integrate:

dy/√y = 2/x) dx

y (-1 2) dy = 2 1 x) dx for both sides to integrate:

2√y = 2ln|x| +c

This Nai Oli c is the integral constant. Next, we're going to solve y:

y = ln|x| +c/2

Square on both sides:

y(x) =ln|x| +c/2)^2

This is the general solution of the differential equation sought.

2.There are a lot of methods, the most intuitive is the early lead, let the plane equation ax+by+cz+d=0, substitute the point coordinates to find which a, b, c are represented by d, because the coordinate origin is not on the plane, so d≠0, can be reduced d

3, Let u=2x 2+y 2,v=x 2=3y 2, then z=f(u,v), and find the derivative using the coincidence function.

On the third day, I watched the total:

108 pages.

98!+99!+100!

From 1 to 98, there are 20 5s, and 10000 contains 4 5s, so the original formula contains 24 5s, which is the factor of 24 to the power of 5.
