A gerund phrase is the subject,

A gerund phrase is the subject,

Gerund phrases as subjects are grammatically related to an event or a process, so they are regarded as singular subjects
Swimming in such a river is dangerous.
Using is as a copula
Do gerund as subject predicate verb use plural form? I only remember that singular and plural are homographs
Swimming is good for our health
Running and jumping are my favorite
singular
Mm-hmm!
Is the predicate verb singular or plural when the gerund is the subject in English
Doing sports make or makes us strong
Doing sports makes us strong singular
It is known that f (x) = 4x + ax ^ 2-2 / 3x ^ 3 (x ∈ R) is an increasing function in the interval [- 1,1]
(1) Find the value range of real number a
(2) If the maximum value of derivative f '(x) of function f (x) on [- 1,1] is 4, try to determine the monotone interval of function f (x)
(3) If f (x) ≤ f '(x0) is constant for all x ∈ [- 1,1], the range of x0 is obtained
(1) When f '(x) = 4 + 2ax-2x & # 178; ∵ f (x) is an increasing function on [- 1,1], f' (x) ≥ 0 is constant, i.e. 4 + 2ax-2x & # 178; ≥ 0 is constant, i.e. X & # 178; - AX-2 ≤ 0 is constant, let g (x) = x & # 178; - AX-2 only need g (- 1) ≤ 0 and G (1) ≤ 0 to ∵ A-1 ≤ 0 and - A-1 ≤ 0 to get the solution of - 1 ≤ a ≤ 1 (2) f '(x
What is the factorial of 0?
What about 1
Factorial means to multiply from 1 times 2 times 3 times 4 to the required number
The factorial of 0 is 1
Given the function f (x) = 4x ^ 3-3x, X ∈ [- 1,1], prove that for any x ∈ [- 1,1], f (x) ≤ 1
Given the function f (x) = 4x ^ 3-3x, X ∈ [- 1,1], prove that for any x ∈ [- 1,1], f (x) ≤ 1
The inflection point can be found by derivative. The second derivative is greater than the maximum value of 0, and the second derivative is less than the minimum value of 0
Why is the factorial of 0 equal to one
This is a mathematical definition
0! = 1, so 0! = 1!
According to the rules, there must be a basis!
If the maximum value of the function y = - X3 + 6x2 + m is 13, then M=______ .
The maximum value of ∵ function y = - X3 + 6x2 + m is 13 ∵ y ′ = - 3x2 + 12x = 0 ∵ x = 0, x = 4, ∵ function increases monotonically on (0,4), decreases monotonically on (4, + ∞), so the answer is: - 19
The factorial of 100! Is 1 * 2 * 4 * 100?
It's 1 * 2 * 3, * 99 * 100
Given that the maximum value of F (x) = - x ^ 3 + 6x ^ 2-m is 12, what is the value of M
Such as the title
f(x)=-x^3+6x^2-m
f'(x)=-3x^2+12x
f'(x)=0
-3x^2+12x=0
x=0 x=4
f''(x)=-6x
F '' (4) = - 24 f (4) maximum
12=-4^3+6*4^2-m
m=20
