5 simple unsolvable equations

5 simple unsolvable equations
1. 1/x=0
2. 2^x=0
3. sqrt(x)=-1
4. abs(x)=-1
5. x=x+1
What did I miss?

I love the "I'm not talking about computer science".

[wistfulgraph]

“You cannot say infinity”
*Negative Infinity*

"I'm not talking about computer science."

Literally the first thing that came to mind when he wrote that. He really is on top of things!

[jordonyang]

As a computer science major I appreciate this guy for clarifying 😂😂

[Asterisk_]

As the days pass by, he gets closer to becoming a Shaolin Math Monk

[lolis]

x=x+1 for Computer Science: 🥳🤠😌🤪😜😘😝😛

x=x+1 for mathematicians: 😞😖😓😣🤬😠😡😩😫

[austinh]

Lets be honest, no real programmer would actually write "x=x+1"
They'd instead use "x++" or "x+=1"

0:01 "some solutions that have no equations" broooo the equations are right there!!

[chrisy]

"Don't say infinity okay?" Had me fucking rolling 🤣 💀

[kerim]

1 and 5 is approximately true for large x

And yes I am an engineer

[qccdizl]

HEY GUYS THE FUNDAMENTAL THEOREM OF ALGEBRA IS INCORRECT, THERE ARE EXAMPLES DISPROVING THAT THEOREM IN THE FORM OF, X = X + N, WHERE N ≠ 0
FOR EX, X = X + 2

[metalheadmaniac]

i have an equation that might not be solvable let's see if you can solve it

hold on I have to go get my math homework

[PriggarGaming]

First one x=tan 90°
Second one x=-tan 90°
Third one x=i^4
Fourth one x=dont know
Fifth one x=tan 90°

[mr.maicrowave]

This is a certifed black pen only moment

[meccamiles]

“Do not say infinity.” Lol, love that. And you’re absolutely right.

[friedwater.]

why did I laugh so hard at “I’m not talking about computer science”

[Anonymous-rudg]

please correct me if im wrong, i might be making a stupid mistake


in equation 3

√x = -1
square both sides
x=1

lets put this in eq 3

√x= -1
√1= -1
+1 or -1= -1
so this is true right?

[mohamedfarouk]

3 and 4 are a matter of definition, we define √ as the positive square root and we define | | as the distance from the origin and, successively, we define any distance as a positive quantity.

1, 2 and 5 give x an infinite magnitude which cannot be a well-defined number in any field.

[MrBombasticccccc]

In 3 )x can be equal to 1, so we will get 2 solutions ie. +1and -1

[xCorvusx]

3 and 4 feel kind of like cheating, since the respective functions were defined to only give positive answers
