Hi guys, sorry i have not been around much but my new job is keeping me busy and I have not got into a routine that gives me flying time yet.
My daughter has come home with some maths homework that i dont know how to do......
Its quite simple (if you know how)..all we have to do is find the tan, cos and sin of some angles in degrees.
I remeber "silly old harry can always have tow of anything"
silly old harry :sin=opposite over hypotenues
can always have: cosine=adjcent over hypotenuse
etc..
i have found a web site that does the conversion for us but i want her to know how to do it on a scientific calculator
if we have 7degrees, the converter gave us tan: 0.1228, cos: 0.9925 and sin: 0.1218
but what do we put into the calculator
if i enter "tan(7)" i get 0.87144, so i gues thats not all there is to it?
any pointers or clues welcome
calculator is a casio fx-85ES (i have looked at the manual but could not find anything)
Cheers guys
