## Silly Questions Amnesty

Got something that's bugging you about maths? Post it below for a no-names-no-packdrill reply. It doesn't matter how silly. If you're worried about a train leaving Manchester at 8am, let me know.

Hello, It is good to receive tips and articles from FlyingColoursMaths in email.  Well, I have been a learner in maths.  You seem to be very well educated in maths and have a lot of good ideas about learning or teaching basic maths.  May I ask you a few questions

## Secrets of the Mathematical Ninja: Converting radians to degrees (precisely)

Some while ago, I covered how to convert degrees into radians (and vice versa) in your head. I missed a trick, though: I didn't tell you about the exact values, which would probably have been a bit more useful. By definition, a circle -- 360º -- is 2π radians, which

## How to do a trigonometry proof: five top tips

First up, a horrible confession: I like teaching the higher-lever core maths modules (C3 and C4), because they're closer to 'real' maths than the AS-level ones. One of the things that sets them apart is the introduction of proofs, usually for trigonometry1. And a lot of students struggle with it

## The Lives* of the Mathematical Ninja: Srinivasa Ramanujan

If you ever reach the upper echelons of mathematical research, you will get a fair number of letters and emails from cranks wanting you to champion their crackpot schemes. It goes with the territory. Some of them are entertaining, most of them are harmless, misguided buffoons, and some are dangerous
