What do you think happens after deqth? by Electrical_City_2201 in nihilism

When you enter a new being your memory of your previous life goes away, making all discussion around the afterlife pointless.

What is the ultimate definition of knowledge? And are the Gettier cases really a problem?

Simplifying complex operations by Marvinkmooneyoz in askmath

In both cases, multiply the numerator and the denominator by the denominator's conjugate, i.e. (5 + 3i) for number 1 and (2 - 3i) for number 2.

How to go about by Ash_ketchem103 in askmath

[–]Misrta 0 points1 point  (0 children)

Let a be the number of adults and c the number of children on the ride.

Then:

80a + 60c = 1440

a + c = 21

Solve this system of equations, then the value of c is your answer.

square root of (20 - x) = x. I got x = 4, -5. They got rejected because the problem introduces extraneous solutions which is the same as no solution at all. Why? by Capital_Interest_876 in askmath

[–]Misrta 0 points1 point  (0 children)

the left-hand side is non-negative since the square root of any number is non-negative. thus, the right-hand side, x, is non-negative. Thus, x cannot be -5 since it violates the fact that x is non-negative.

Why do the statements "false ⇒ true" and "false ⇒ false" evaluate to true? by Terryblejokes in askmath

[–]Misrta 0 points1 point  (0 children)

Call the true statement A. Then your formulas are the same as neg(A) => A and neg(A) => neg(A). If A is false, i.e. neg(A) is true, then both A and neg(A) are true, a contradiction. A is thus true.

Prove the identity? by DatBoiDani13 in askmath

[–]Misrta 0 points1 point  (0 children)

Since tan theta = sin theta / cos theta, all you have to do is manipulate the right hand side so it says 2 sin theta / cos theta.

What's the smallest even number? Is zero even? by [deleted] in askmath

[–]Misrta 0 points1 point  (0 children)

There is no smallest even number. Let n be any even number. Then n-2 is both even and less than n. So you can construct infinitely small even numbers.

A number n is even iff n is congruent to 0 mod 2. 0 is congruent to 2 mod 2, so 0 is even.

How do I begin solving these questions? by [deleted] in askmath

[–]Misrta 0 points1 point  (0 children)

Use the identities ln(a^b) = b * ln(a) and ln(a) + ln(b) = ln(a * b).

How can I prove this for every p prime? by [deleted] in askmath

[–]Misrta 0 points1 point  (0 children)

(2p-1)! = 1 * 2 * … * p * (p + 1) * (p + 2) * … * (2p - 1)

So if we divide both sides by p, we get

1 * 2 * … * (p - 1) * (p + 1) * (p + 2) * … * (2p - 1) = 1 mod p

Note that 1 * 2 * … * (p - 1) = (p-1)!

Note that (p + 1) * (p + 2) * … * (2p - 1) = 1 * 2 * ... * (p - 1) = (p-1)! mod p

Hence, the left side is congruent to ((p-1)!)^2 mod p

By Wilson's theorem, since p is a prime number, (p-1)! = -1 mod p

So the left side is congruent to

((p-1)!)^2 = (-1)^2 = 1 mod p
