Could someone help me out with this please

Im woring out an angle and i get 21.45 (not the real number) then I push the degrees minutes and seconds button and I get 21 degress 20 minnutes 34 seconds (not real numbers)

Which is the corret result?

What happens when you push that button?

Up to now ive just let the angle = 21.45 degress, but now im not sure if that is right.

any help would be awesome.

Time to renew the microwave i think RM.........

one is decimalised you tit.

ie .45 of a degree = 20 minutes and 34 seconds

1 minute = 1/60th of a degree

1 second = 1/60th of a second = 1/3600th of a degree

There are times I just love having you around - that diplomacy, sensitivity and unerring sense of when to back off !!!!

So when I work out sine(angle) I should push that button to get the true angle? in school they just leave it?

[The_Dover]

what are you using it for?

I usually just leave a decimal angle. easier to write down and i'm a lazy cunt

this is a good site for all sorts of conversions, which shows some workings for reference

Working out the angle of friction... basiclay tan-1(insert number here) = angle of friction.

So what your saying is, the decimal number is correct but slightly wrong? i.e I wouldnt get marked wrong in an exam?

If it's for an exam, then it all depends on what answer the markers are expecting......'correct' exam answers are not always real-world correct. They are quite often limited by what the curriculum has specified be taught that year and what level is being taught. Was a hard lesson for me to learn that what I was taught at age 15/16 was totally different to age 17/18 then again at Uni! Now I just accept that there's always going to be a next level that I will never understand or be privvy to! LOL (quantum mechanics was my breaking point!!)

If you have been taught to use decimals, then go with that. If you have been taught to work it all out long-hand (which I very much doubt these days) then go with the conversion to degrees/minutes/seconds.

(If it's maths then the decimal is probably all they are after, rounding errors are no great issue. If it were physics then I would expect they would be after the absolute answer)

But then I've not been at school since 1991 and I left Uni in 1997, and both of those were in the UK, so what do I know?!

Oh dear god .. i havn't had a laugh like that in ages .. .. i had no idea about that either .. but the reply was brilliant .. more bling for you, you magnificent bastard. .. ha ha

If you want to get full marks just write them both, knob.

Ahhhh just forget it. I left school 29 years ago (when we had to work those things out without a calculator) and I've never had to use it.

[Oakie thinks for 20 seconds after typing first sentence and then begins to type again ...]

OK. Now I'm curious. Just what sort of occupation would you use that sort of stuff in? Seriously ... not taking the piss.

[The_Dover]

surveying, engineering.

[Jamezo]

Decimal is perfectly fine, if you want to piss around with arbitrary and distasteful descriptions of angle!

How about 0.374373125? Real men don't need units.
