Anonymous users2024-02-07In fact, the constant can be extracted directly, if you have to treat it as a variable, you should use the derivative formula.
2x·4-(x^2)·0}/16=x/2
First of all, you need to understand the concept of constants, coefficients are constants and exponents are constants, so you must follow the law of derivative.

Anonymous users2024-02-06This derivation is generally a derivation of something, but it is not usually specifically pointed out. If you ask you about this x 2 4, you can say that you are derivative of x. This can also be written as a quarter x square, and the derivative is found separately.
First, the derivative of 1 4 is identified, and the result is multiplied by x squared, and then the derivative of 1 4 multiplied by x squared. The sum of the two is the final result.
Although the derivative of y=x 3+4 is not specified, we generally know that the derivative of x is known. That is, the derivative to the right of the equality sign.

Anonymous users2024-02-05In addition and subtraction, the constant derivative is zero, but at this time 1 4 is a constant coefficient, which is also a multiplication, and the derivative of x 2 is 2x, then the coefficient is unchanged and directly multiplied with it, so that it is 2x 4 simplified to 1 2*x
y=x^3+4
y'=3x^2

Anonymous users2024-02-04Answer: Finding the derivative of x 2 4 is equivalent to finding the derivative of x 2 and multiplying it by 1 4.
If the denominator is squared, it should be: 2x*4-0 16, you missed the multiplication. In addition, the constant derivative is 0.

Anonymous users2024-02-02Summary. x -4 +x +4) 4 derivative.
Hello, I'm glad to serve you, the derivation of this problem is actually the derivation of the composite function, first look at the derivation of a circle as a whole, and then the derivation in parentheses, the process of teasing the brightness of the mountain cavity and the final result, I have written it on paper for you to understand.
I don't understand, can you talk about it?
In terms of the addition and subtraction of the squares of x, we see him as a whole n, that is, let's find the derivative of n to the power of 4.
That is, 4 n to the 3rd power.
This is what we learned about the derivative of a simple function.
But n and x squares add and subtract.
We also need to do a separate derivative of n.
This is an expression for a composite function.
The whole equation is composed of two functions, which are to the power of y n, and the square of n x is added and subtracted.
Isn't it particularly clear, can you write about it?
Good pro received your request.
This is question A of Question 6.
This is question b of question 6.
Question A is not very clear.
You are 1/2 of x where you don't understand putting a pro.
The n-power derivative of x is n-fold to the n-1st power of x.
I really can't do the second question, take a look.
The key to solving the problem is that the lead is not leading, and the lead is not leading.

Anonymous users2024-02-01Summary. 1. By assuming: let y=x and give x an increment x, then correspondingly, the increment of the function y=(x+ x) -x =2x x+(x).
So: divide both sides by x, you get y x=2x+ x, and take the limit on both sides to get: y = x 0lim( y x) = x 0lim(2x+ x)=2x
x +4 how to find a derivative.
How to find out.
The derivative of x is 2x
The derivative of 4 is 0
x +4, so the derivative of the whole is 2x
Why is the derivative of x 2x
1. By assuming: let y=x and give x an increment x, then correspondingly, the increment of the function y=(x+ x) -x =2x x+(x). So:
Divide the two sides by Kaiyan mu x, you get y x=2x+ x, and take the limit on both sides to get: y = x 0lim ( y jujube x) = x 0lim (2x + x) = 2x
2. According to the formula: y=x of the derivative of jujube cultivation, where n is a constant, so: y =nx is substituted with n=2, that is, the chain brother has to shed the rock to attack y = 2x
In middle school, we don't need to know the first way, we just need to remember the second way and apply it in calculations.
Are all derivatives of constants 0.
Yes.
25x24, if this problem is calculated in a simple way, we first need to decompose 24 into 4 6, and then substitute this formula into the original formula, that is, 25 4 6, we can calculate 25 4 = 100, and then use 100 6 = 600, so that we can quickly calculate that the answer to this problem is 600.
If you start with y as a distance, the equation may be easier to understand. d = root number (x 2+4x+13) + root number (x 2-2x+2) = root number ((x+2) 2+9) + root number ((x-1) 2+1) = root number ((x+2) 2+(0-3) 2) + root number ((x-1) 2+(0+1) 2). This is the sum of the distances between the point (x, 0) and the point (-2,3) and the point (1,-1). >>>More
