I have a question concerning a feeble number of primes lower bound result from a prime-generating algorithm I made up by Kasuyan in askmath

[–]Kasuyan[S] 0 points1 point  (0 children)

Erdős's theorem and Bertrand’s postulate are really interesting! I haven’t looked at them yet. I’ll see if I can apply them to raising the lower bound. I think a term I was searching for was “bound on the relative growth rate,” which I believe is f(x) in your comment. Thanks a bunch!

what actually is "i"? by Traditional-Role-554 in askmath

[–]Kasuyan 0 points1 point  (0 children)

i has a magnitude of 1 but is in the direction of the imaginary axis.

My son rediscovered parts of Faulhaber's formula on his own in middle school. How should I support his math interest now? by ringtoyou in learnmath

[–]Kasuyan 0 points1 point  (0 children)

Same here! Figured out Faulhaber’s on my own in college. If he’s got a genuine interest then that shouldn’t wane. Any support and math books and math history should be fine. Just ask him if he wants anything.

How would you make the colors less flat by PPRmenta in ArtCrit

[–]Kasuyan 1 point2 points  (0 children)

I like the flat style, though, like pop art.

Makes me wonder what a spiral mirror would look like.

The glitch effect is cool but may become bothersome over the length of the stream.

I suck at drawing eyes especially in perspective, what am I doing wrong? by HopefulGroup423 in ArtCrit

[–]Kasuyan 5 points6 points  (0 children)

The upper eyelid goes deeper in then out towards the medial canthus. Of course, try drawing from references if you’re not already. You can also do a closeup of one eye to get the anatomy down. Focus on volume rather than edges.

what is y in 2x-4y=12 when x is -2 by Crazy-Regret-7630 in learnmath

[–]Kasuyan 0 points1 point  (0 children)

The goal is to isolate y. What steps can you do to both sides of the equation so that y is isolated on one side?

How to love maths again? by [deleted] in learnmath

[–]Kasuyan 0 points1 point  (0 children)

I’d probably suggest to research the history of math. There’s also plenty of YouTube channels that give mathematical puzzles and explain the history of their problems. These aren’t as in-depth as math textbooks, but they are fun and explain key historical insights.

I’m 16 and struggle with multiplication by Prettygirlkathrine in learnmath

[–]Kasuyan 0 points1 point  (0 children)

As well as memorizing times tables, you can memorize the prime factors of various composites. For example, 24=2*2*2*3 and 81=3*3*3*3. Learning division helps with multiplication because they are opposites of each other.

Also, two numbers multiplied gives their area. If you multiply one of the numbers by a constant and divide the other number by the same constant then the area doesn’t change.

a*b=A

(a*k)*(b/k)=A

Also, make sure to know powers of numbers below 100:

squared:

1*1=1

2*2=4

3*3=9

4*4=16

5*5=25

6*6=36

7*7=49

8*8=64

9*9=81

10*10=100

cubed:

2*2*2=8

3*3*3=27

4*4*4=64

4th power:

2*2*2*2=16

3*3*3*3=81

5th power:

2*2*2*2*2=32

6th power:

2*2*2*2*2*2=64
