I wrote this for math class, does it make sense?A very famous equation, Euler’s identity relates the seemingly random values of

pi, e, and the square root of -1. It is considered by many to be the most beautiful equation in mathematics.
A more general formula is

e^{i x} = \cos x + i \sin x

When x = \pi , the value of \cos x is -1, while i\sin x is 0, resulting in Euler’s identity, as -1 + 1 = 0.

Also please don't hate I am only in sixth grade...

Answer:

5 = 5

5 < 6

7 > 6

Step-by-step explanation:

The two slashes is the equal sign, comparing two numbers that are of the same value. The sign below that means "less than," and 5 is less than 6. The sign below the "less than" sign is the "greater than" sign, and in the given example, 7 is GREATER THAN 6.

Prove that the sum of all natural numbers is -1/12.
ankoles [38]
This is not true. The infinite series


\displaystyle\sum_{n=1}^\infty n

converges if and only if the sequence of its partial sums converges. The k-th partial sum is

\displaystyle\sum_{n=1}^kn=\frac{k(k+1)}2

but clearly this diverges as k gets arbitrarily large.

You want to walk from home to a clothing store that is 3/4 miles away. You stop for a rest after 1/2 miles. How much farther do
dmitriy555 [2]

Answer:

1/4 miles.

Step-by-step explanation:

If I want to walk from my house to a clothing store 3/4 of a mile away, this implies that the location is 0.75 miles from my home.

Now, if after walking 1/2 mile I decide to stop, I will have traveled 0.5 miles in total. In this way, when I get back on my way, I will have to travel 0.25 miles to reach my destination (0.75 - 0.50).

Therefore, since 1 divided by 4 equals 0.25, I have to walk 1/4 mile to reach my destination.
