1. DDz Quorum Friar Posted March 30, 2009 1. DDz Quorum Share Posted March 30, 2009 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 Friar Quote Link to comment Share on other sites More sharing options...
1. DDz Quorum Sid Posted March 30, 2009 1. DDz Quorum Share Posted March 30, 2009 Friar, try this: Your calculator isn't in the right mode. Normally your calculator is in 'degree' mode, but it looks as if yours is in radians. It simple to change though. Just press the 'mode' button on the calculator (should be along the top somewhere) twice, and then this will come up: Deg Quote Link to comment Share on other sites More sharing options...
