What a frighteningly horrendous equation – you might think. For sure, it would mean something evil – a formula for nuclear devastation – some would say.

But nothing could be farther from the truth. What this ” frightening” equation represents is :


Yes – the ‘heart’ symbol – a universally accepted symbol of love. Who would have guessed? In fact mathematicians call this a cardioid. Some variations of the equation gives slightly different versions of the curve( for the math guys, it’s a curve).


The heart shape isn’t the only ‘design’ that has an equation for itself. In fact there are a lot of  complicated looking equations, which when translated, gives beautiful looking graphs.

Let’s look at some of them.
