How to draw a heart with pen?

So uh yeah… It is a nightmare that I COMPLETELY forgot trigonometry!!
How do you draw a heart with pen from point A to B. Illustration:

Thanks! <3

Perhaps you could try finding a circle script, stopping it at a certain, adding a “V” shape at the top, and redoing it at the other side? I don't have any examples tho, sry XD

Gonna try it. Though I doubt that the top sides of the heart are semi-circles/ellipses…

Edit: Ok… That went horribly wrong D:

Found this:

I have a liiiitle question. What does |x| represent?

deck26

It's the absolute value of x.

Thanks!!! Now I can start with the equations!
I still have no idea why I don't remember any of these :/

Hey, I just threw this together.

Nice! Question though, how would you draw it from point A to B (as illustrated on the first post)?

Mean while I got a neat little equation, but suffers the same issue. How do I center it around point A and B??
The basic heart: https://scratch.mit.edu/projects/146403009/

x=16sin^3(t)
y=13cos(t)-6cos(2t)-2cos(3t)-(-1cos(4t))

If the centre has coords x and y then all movement needs adjusting for that. If you have a function y=f(x) you'd instead use y=ycentre + f(x - xcentre).

I think that's right.

What do you mean by from point A to B? Where would these points fall on the heart?

Hope I understood that correctly!

Let's say 4 points instead of 2. Join them and you get a square/rectangle, the heart should be inside the square/rectangle, centering on it.

For @NitroCipher's version you'd need to replace the goto 0,0 with the coords between A and B (average of Ax and Bx, average of Ay and By) since all the moves are relative other than the two goto's.

Thank you! Those equations gave me the idea I was looking for! I have almost got exactly what I needed https://scratch.mit.edu/projects/146403009/#player
Will play around with the values a bit. Thank you to everyone who helped me!

I've added scaling to my remix.

Happy to delete my remix when you're happy you have what you want.

I think I am ok with the results now. Also, why delete the remix? Somebody may stumble upon something similar, and need that!
Thanks again

What's wrong with the solutions above?

if you still need help please create your own new topic rather than necroposting.
