^getting a bit old

 

A simple proof that 9+10=21

 

The Law of Conservation of Matter states that matter is not destroyed, simply rearranged

In Roman numerals: 9=IX, 10=X, 21=XXI

 

Hence 9+10=IX+X=IXX

=XXI=21

 

QED.

IXX and XXI ain't equal. Correct me if I am wrong please

This seems wrong, this can be simplified further

 

Convert cos to  - sin

 

-3x - 4 sin^3 (x^2)

 

The power of sin can remain the same unless you want to simplify it im not sure, times 2 by 3x - 4 leaving x on its own

 

-2(3x-4) sin ^3 x

 

The answer is -6x+8 sin^3 x

 

No this is the answer (hopefully)

 

3x - 4 cos ^ 3 (x^2)

 

- 3x - 4 sin ^3 (x ^2) 

 

Chain rule

 

X ^ 2 is now  2x         y now becomes = -3 sin^3

 

2x * -3 sin ^ 3 * x^2

 

Answer: 6x sin^3 (x^2)

 

Someone can correct anything if im wrong  :P

- 3x - 4 sin ^3 (x ^2)

X ^ 2 is now  2x         y now becomes = -3x - 4 sin^3

 

2x * -3x - 4sin ^ 3 * x^2

 

Answer: -6x^2 - 8x sin^3 (x^2)

 

Someone can correct anything if im wrong  :P

I wouldn't know what to correct.  :blink:

why do you guys ask so many simple questions .-.

• Write down your age.

Multiply it by 1/5 of 100.

Add on today's date (e.g. 2 if it's the 2nd of the month).

Multiply by 20% of 25.

Now add on your shoe size (if it's a half size round to a whole number).

Finally subtract 5 times today's date.

Show me you final answer!              i like this trick :D
