hi every one....
iam from electrical background. I am designing power factor measurement circuit using 89c51. I want to convert the time gap between two consecutive pulses into degrees (angle = 100pi*time). then i have to get the cosine of that angle. my problem is, i didn't find any technique to get cosine of that angle. please help me.
thanQ.
