A literal equation is one that has several letters or variables. Examples include the area of a circle (
$A=\mathrm{\xcf\u20ac}{r}^{2}$ ) and the formula for speed (
$s=\frac{d}{t}$ ). In this section you will learn how to solve literal equations in terms of one variable. To do this, you will use the principles you have learnt about solving equations and apply them to rearranging literal equations. Solving literal equations is also known as changing the subject of the formula.

You should bear the following in mind when solving literal equations:

We isolate the unknown by asking what is joined to it, how this is joined and we do the opposite operation (to both sides as a whole).

If the unknown variable is in two or more terms, then we take it out as a common factor.

If we have to take the square root of both sides, remember that there will be a positive and a negative answer.

If the unknown variable is in the denominator, then we find the lowest common denominator (LCD), multiply both sides by LCD and then continue to solve the problem.

The area of a triangle is
$A=\frac{1}{2}b\xc3\u2014h$ . What is the height of the triangle in terms of the base and area?

We rearrange the equation so that the height is on one side of the equals sign and the rest of the variables are on the other side of the equation.

fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.

what is the actual application of fullerenes nowadays?

Damian

That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

what is the Synthesis, properties,and applications of carbon nano chemistry

Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.

Do you know which machine is used to that process?
