XY LOVE

A beautiful heart, fruit of my love for hurz <3 who inspired me to create it. 

The heart has been made using this parametric equations: 

X=16*sin^3(t)
Y=13*cos(t)-5*cos(2t)-2*cos(t)-cos(4t)

The X part has been simplified:16*sin^3(t) = (3/4)*16*sin*(t)-(1/4)*16*sin(3t) and the operations have been performed simply by using two generators in series, with one backwards.

The Y part has been calculated analogically using an OP amp as an adder/substractor, the cosines have been created with a 90º phase shift. 

I want to make sweet love with you hurz, call me!

Nice, but probably hurz will try to find something he could do better, before say "yes" to you.

It could have been made without the adder/substractor, just by doing what I did with the X component, placing all the sources in series with polarity depending of the sign of each cosine in the equation. But it helps to represent it by adjusting the gain.

Pretty awesome Victor805! Hurz will possibly never know how appreciated he is. Many others also impart their knowledge to the masses. Hurz might have been the 1st to download EC or close anyway. Thanks to the many who keep it tech related

Generators work following mathematical formulas, just combine them correctly to create the desired mathematical expressions so you can plot anything you wish.

Victoria, why the hell you make a secret from were you got that knowledge? Its pretty clear, after reading your fuzzy explanations how it work that you actually have no idea what it is all about. At least you should have given a link were you copied that math part. You feel bored and you are boring. http://knowyourmeme.com/photos/698419-science

I never said I came up with the formula by myself, I'm not a math girl, I did simplify the expression and implement the circuit by myself, though, Hurz-kun
