What's the use of 1, 2, 3, 4, 5, 6, 7, 8, 9, 0 on a calculator if FX-82ES/99 1ES:
1. On …
Step 2: Ways
3. Starr
4. 1
5. Enter the data.
6. alternating current
Move in
8.5
9.3
10 =
1 1 standard deviation of results
12 2, and the standard deviation is the square difference.
What is the use and significance of the "GT" key on the calculator? 2.8. Power-on/clear key (ON/AC): Press this key to indicate power-on or clear the values in all registers. 2.9. Clear key (c): During digital input, press this key for the first time to clear all values except the memory contents. 2. 10. Clear input key (CE): Press this key during digital input to clear the value in the input register and display "0". 2. 1 1. square root √: displays the square root of the positive input number. 2. 12. Interrupt digital input. 2. 13.M-: Subtract the currently displayed value from the stored content; Interrupt digital input. 2. 14.MRC: press this key for the first time to call up the memory content, and press it for the second time to clear the memory content. 2. 15.MR: Call the memory contents. 2. 16.MC: Clear the memory contents. 2. 17.GT: press the GT key. Press AC or C to cancel the GT display sign.
What are the buttons on the calculator for? I won't talk about the common calculation commands. Let's talk about uncommon and function keys first.
MC: clear storage
MS: save in memory
MR: read storage
M+: add storage
M-: subtract from the storage.
Usage: store a value for the call, such as press 0.000025 and then press Ms. When you want to calculate 0.000025*2, you can press MR*2.
Clear the currently entered number.
C: It is the evolution of CE to clear all the current equations and results.
Invi or shift, which can be said to be the shift key, can be used to switch the positive trigonometric function and the negative trigonometric function.
Mod: Find the modulus, that is, find the remainder or integer division to find the remainder. For example, if the 5/3 remainder is 2, press 5Mod3=
Int: Take the integer part, for example, 5/2 takes the integer part as 2, press (5/2) and then press int.
AND: Bitwise AND
Or: bitwise or
XOR: Bitwise XOR
Lsh: move to the left
Not: bitwise inversion
Sine, cosine, tangent, hyperbolic sine, hyperbolic cosine, hyperbolic tangent
The purpose of calculator is to calculate numbers and things.
What trigonometric function sinx is sin on the calculator?
What key is the date on the calculator? On the general scientific calculator, the date key is replaced by the M+ key.
What is the e on the calculator? E is the base of natural logarithm, that is, the base of ln logarithm.
Is a very common mathematical constant.
e = lim x→∞( 1+ 1/x)^x=2.7 18
Hope to adopt. Thank you.
