You can't convert sin40 to a fraction. Because it's an irrational number. Only for very few of the sine results will be able to be converted to a fraction.

Exactly.

If you're referring to the exact results or maybe having it convert in using pi (e.g. 3pi/2.... blah blah).... then I know of no calculator that will do this.

I worked out the answer and am very happy

you worked out how to express an irrational number in the form p/q?

p and q aren't probably rational.

y=mx+b

 

[gurmies]

y=mx+b

lolwut

p and q aren't probably rational.

So you're saying she was able to express sin(40) in a closed form? As if...

No, sorry guys couldn't work it out to be rational, it's not possible.

Thanks though
