FOR , TO FIND LOG

HOW TO FIND LOG BY USING SIMPLE CALCULATOR??????????

1.    WRITE 2.7183

2.    TAP ‘ ‘ (i.e. Square Root) 12 times

3.    DEDUCT ‘ 1 ‘                          (= 0.00024417206)

4.    PRESS ‘ M+ ‘ KEY

5.    WRITE THE NO. OF WHICH ,YOU WANT TO FIND LOG

(E.G. LOG 5 THEN WRITE 5)

6. TAP ‘ ‘ (i.e. Square Root) 12 times

7. DEDUCT ‘ 1 ‘

8. PRESS ‘ ÷

9. PRESS ‘ MRC’

10. PRESS ‘ = ‘ (ANSWER WILL BE IN BASE e)

IF TO FIND IN THE BASE OF 10 THEN :-

11. PRESS ‘ X ‘ (i.e. MULTIPLY BY) AND WRITE 0.4343

12. PRESS ‘ = ‘ (ANSWER WILL BE IN BASE 10)

NOTE :- ABOVE 1ST  THEREE STEPS WILL BE COMMON SO IT IS BETTER TO

REMEMBER THE VALUE ‘ 0.00024417206 ‘

FOR EXAMPLE :- LOG 5 = 0.6990

NOW WE WANT TO FIND LOG OF 5 :-

1.    WRITE 0.00024417206

2.    TAP ‘ M+ ‘ KEY

3.    WRITE THE NO. YOU WANT TO FIND THE LOG i.e. 5

4.    TAP ‘ ‘ (i.e. square root) 12 TIMES  (= 1.00039300638)

5.    DEDUCT ‘ 1 ‘  (= 0.00039300638)

6.    TAP ‘ ÷

7.    TAP ‘ MRC ’

8.    TAP ‘ = ’ (1.6095 – ANSWER IN BASE e )

9.    TAP ‘X’ (i.e. MULTIPLY) BY 0.4343 THEN TAP ‘=’

(0.6990 – ANSWER IN BASE 10)

NOTE FOR ABOVE EXAMPLE :-

WE CAN DIRECTLY DIVIDE BY 0.00024417206 IN STEP – 7 INSTEAD

OF USING  ‘MRC’ BUTTON , IN SUCH CASE , THERE IS NO NEED OF

STEP – 1 & 2. YOU CAN DIRECTLY START FROM STEP -3

FOR, TO FIND ANTILOG .....

**HOW TO FIND ANTILOG BY USING SIMPLE

CALCULATOR?

STEPS TO BE FOLLOWED :-

1.   WRITE THE NO.

2.   TAP ÷ (i.e. divide ) by 0.4343 & = (equal to)

3.   TAP X (i.e. Multiply ) by 0.00024417206

5.   TAP ‘X & = ‘ (MULTIPLY & EQUAL TO) 12 TIMES SIMULTANEOUSLY.

FOR EXAMPLE :- LOG 5 = 0.6990

NOW WE WANT TO FIND ANTILOG OF 0.6990 THEN

1.   0.6990

2.   (0.6990 ÷ 0.4343) = 1.60948653004

3.   (1.60948653004 X 0.00024417206) = 0.00039299164

4.    (0.00039299164 + 1) = 1.00039299164

5.    (1.00039299164 X THEN =) FOR 12 TIMES

= 4.9997 ~ 5 (i.e. log 5)

To find log following steps:

1. Enter the value for which you have to find log
2. Press sqrt button 15 times
3. Subtract 1 from that no.
4. Divide it by 0.00007027178
5. Press equals to button.

Example:

1. To find log of 2
2. Press 2 in calculator
3. Press sqrt button 15times (Ans: 1.00002115339)
4. Subtract 1from that (Ans: 1.00002115339 - 1 = 0.00002115339)
5. Divide by 0.00007027178 (Ans: 0.00002115339 / 0.00007027178 = 0.30102254418)
6. Answer is 0.3010 (upto 4 digit)

In simple calci we found log on base 10 from simple trick...

1) press no. whoes log you want to find   (e.g. log2)

2) press 19 times underroot button    (1.00000132206)

3) subtract 1      (1.00000132206-1 = 0.00000132206)

4) multiply by 227695  (0.00000132206 * 227695 = 0.3010264517
