Excel input for 7671 calculation

lyledunn

Could any one assist this old duffer? I have successfully put together a fairly comprehensive circuit calculation spreadsheet in Excel for circuits up to and including 16mm2. However, can anyone advise how I can enter a cell instruction to convert Cos theta to the sine of the angle. For example power factor is 0.8 and sine of same angle is 0.6. All I want to do is enter 0.8 into a cell and the corresponding cell correctly inputs 0.6.

    as above pythagoras is your friend. you know the cos, that is adjacent over hyp,

    or exact adjacent if  hyp is 1

    and  diff of squared hyp and squared adj gets you the squared opp.

    no need to think about rads or degrees

    Not sure if that is helpful or not. I may come back when the beer has worn off..
