Total Posts: 1189 | cheaters way : in base 13 6x9 IS really 42 but...
maybe deep thought made a mistake:
instead of (1+5)*(8+1) which is the real question, maybe it did 1+5*8+1 and forgot the parentheses, there by changing the order of operations....
plus you can literally turn any number into 42 with the basic 4 functions, sqrt, and trig functions.
try it!

Total Posts: 623 | I'm sure everyone has seen these... Right?a = b + c
a(a-b)=(b+c)(a-b)
a^2-ab=ab-b^2+ac-bc
a^2-ab-ac=ab-b^2-bc
a(a-b-c)=b(a-b-c)
a=bx=y
x^2=xy
x^2-y^2=xy-y^2
(x+y)(x-y)=y(x-y)
x+y=y
y+y=y
2y=y
2=1 sqrt(-1)=sqrt(-1)
sqrt(1/-1)=sqrt(-1/1)
sqrt(1)/sqrt(-1)=sqrt(-1)/sqrt(1)
sqrt(1)*sqrt(1)=sqrt(-1)*sqrt(-1)
1=-1 *yawn* Nap time...

π=π
sin(π)=sin(π)
sin(π)=0 and sin(3π)=0, so:
sin(π)=sin(3π)
π=3π
1=3

a(a-b)=(b+c)(a-b)
a^2-ab=ab-b^2+ac-bc
a^2-ab-ac=ab-b^2-bc
a(a-b-c)=b(a-b-c)
a=b
This is another divide by 0. You're also dividing out roots. there is nothign stoppign a from equaling b though. A could equal 2b, 3b, 4b, 5b+1/2c.
x=y
x^2=xy
x^2-y^2=xy-y^2
(x+y)(x-y)=y(x-y)
x+y=y
this lookes like it works, but since x-y = x-x = 0, you've divided by 0, which is of course not allowed and results in a false answer.
£k=£k
sin(£k)=sin(£k)
sin(£k)=0 and sin(3£k)=0, so:
sin(£k)=sin(3£k)
at this step, you aren't actually taking out the sin, you are taking the inverse sin of each side. 3£k and £k are outside the range of inverse sin.
i'll do the sqrt one later.

Any increment of π will equal the original value in the sine equation, and taking the arcsine merely cancels out the sine (like taking the square root of x^2).

Increasing pi will not equal the original (compare pi/2 to 3pi/2). It's outside the range of inverse sin, which is what i said. Arcsine is just another way of saying inverse sin (on calculator it looks like sin to the -1 power). The square root is the inverse function of x^2 (for x>=0). If inverse sin was allowed to continue to infinity like sin does, it wouldn't be an actual function, violates vertical line rule, so that's why it's limited in domain and range. |

Total Posts: 2 | your calculation is lame because:
1- u divided by a number with no condition on it so it might be zero
2- the sin function is a periodic function that means it repeats itself so u get same answer but you technically are in a new period
so the simplest example is ur watch. 12 pm and 12am
look at ur watch and the hands will be in the same place indicating the same value but u r in a new period
or 12 am on the 3rd of this month and 12 am on the 4th of the same month it is same value but different year
same if u say the 3rd of this month and the 3rd of the next month
or change the year .........
so it is all periodic
3- yes 6x9= 42 and u didn't waste u time learning mathematics because u learned a bit of it and to get this point u need a better back ground
so see why 6x9 = 42
Look at how you usually count. 6 x 9 = 54. But what is 54? It is 5 groups of 10 plus a group of 4 ones.
What is 133? It is 1 group of 10^2 (otherwise known as 100), plus 3 groups of 10 (usually called 30) plus a group of 3 ones.
Now, in base 13, you count by 13's and not by 10's. So,
6 x 9 = 42 and what does that mean?
Well, it means 4 groups of 13 plus a group of 2 ones. Translate that back into the counting you know: 4 groups of 13 plus a groups of 2 ones; which is 52 + 2 = 54.
hope that helps |
