(1/cos) multiplied by x? Or cos-1x?

All that calculation crap has no use, it just makes those who can do it feel like they got one up on the average man in the street. One day the average man will give everyone who isn't average the finger...oh yes! ;)
That's a large chunk of GCSE maths that's not very helpful - no wonder people can't be bothered with it.
