What is the CE key on the electronic calculator

C on the calculator means to clear, which is used to restore the calculator to the start-up state. CE only means to clear the current number, which is used to clear the current input number back to the 0 state
The C key is the clear key
CE key is error correction key (short for clear error)
What is the CE on the calculator______ Key
The CE key on the calculator is the clear key
What does the CE key mean on the electronic calculator
Clear key
What do the AC and CE keys on the calculator represent
All clear key (AC): press this key to clear the values in all registers
Clear input key (CE): pressing this key during digital input will clear the value in the input register and display "0"
AC = All Clear
CE = Clear Entry
Find the maximum and minimum values of the function y = x3-3x in the interval [0, 2]
Let y ′ = 3x2-3 = 3 (x-1) (x + 1) = 0, then we get x = 1 or x = - 1 ∵ y | x = 0 = 0, y | x = 1 = - 2, y | x = 2 = 2, and the maximum value of the function y = x3-3x in the interval [0, 2] is 2; the minimum value is - 2
If the vectors E1 and E2 are not collinear and the real numbers x and y satisfy (3x-4y) e1 + (2x-3y) = 6e1 + 3e2, then the value of X-Y is equal to?
A 3 B 4
C 0 D 2
3x-4y=6
2x-3y=3
So X-Y = 3
Calculator symbol
For example, if you calculate the area of a circle, multiply π by the square of the radius. If you calculate the perimeter, multiply π by twice the radius or diameter. If you calculate the arc length, multiply π by the angle of the sector, then multiply the radius, and then divide by 180 degrees
The satisfactory answer is selected from the bottom right corner of the satisfaction point
The solution of the equation 4x-2m = 3x-1 is twice that of x = 2x-3m
By solving the equation x = 2x-3m, we can get: x = 3M, by solving 4x-2m = 3x-1, we can get: x = 2m-1, ∵ the solution of the equation 4x-2m = 3x-1 about X is twice that of the equation x = 2x-3m, ∵ 2 × 3M = 2m-1, ∵ the solution of the equation 4x-2m = 3x-1 about X is twice that of the equation x = 2x-3m, we can get: M = - 14. A: when m = - 14, the solution of the equation 4x-2m = 3x-1 about X is twice that of the equation x = 2x-3m
Factorization x ^ 6 + 2x ^ 3Y ^ 2 + y ^ 4
(x^6)+(2 x^3 y^2)+(y^4)
What is factorization equal to?
sorry
At the end of that second, I could do it
Who gives the best answer
(x3)2+2 x^3 y^2+(y2)2
=(x3+y2)2
I want it. I want it
Given that f (x) = xlnx, G (x) = x cubic + ax - x + 2, find the monotone interval of function f (x) and the minimum value of function f (x) on [T, t + 2] (T > 0)
(1) If f (x) = xlnx, f '(x) = LNX + 1, Let f' (x) = 0, then x = 1 / E
X0,
It shows that f (x) monotone decreasing interval (0,1 / E), f (x) monotone increasing interval (1 / E, + ∞)
(2) Finding the minimum value of F (x) on [T, t + 2] (T > 0)
If t + 2
