LON-CAPA Help

If the answer to your LON-CAPA problem is

2x²+6x+ 4
3

You can enter any of the following:

```
2x^2+6x+4/3
```
```
2*x^2+6*x+4/3
```
```
2(x^2+3x+2/3)
```
or any other expression that is equivalent to the answer

However, if the answer to your LON-CAPA problem has more than one variable, such as the following:

2xy+3x

You will need to enter the * for all implied multiplication, for example:

```
2*x*y+3*x
```
```
x*(2*y+3)
```

The computer can figure out that 2x is 2*x because it is a number times a letter, but it can't tell if xy is a two letter variable or if it is x*y. Also, it is unclear if exp is meant to be the exponential function or e*x*p.

If your answer is:

√

4x

enter the following as your answer:

```
sqrt(4x)
```
```
2sqrt(x)
```
```
2*sqrt(x)
```

Note that LON-CAPA expects expressions, not equations. So

y=x^2

would not be recognized.
