Writing a formula. (1 Viewer)

[Paj20]

For most papers i have noticed it asks to 'write an equation or formula' for something. Is there a trick to doing it? I always seem to get the formula wrong.

Just read the question carefully. It usually says something like "write an equation for length (l) in terms of width (b)." So you'll need your answer to say l = ... with b somewhere in the right side.

Hope that makes sense.
