Your inputs from above should spit out 17.4 and 9.9 respectively.
Now. Who's working on the Q and D spread calculator?  |
Ok, I think I'm close to cracking this. I figured out the radian functions on my calculator are a different set of buttons with the "degree symbol" after it, ironically (see below)
La = asin˚ (V sin˚ A / (V ^ 2 + T ^ 2 - 2VT cos˚ A) ^ 1/2)
V=target speed
T=Torp speed
A=track angle
When I input the following like before
V=9
T=30
A=75
...I get
15.5 for a lead angle. Not the 17.4 Dorjun said I should get but closer. Anyone see any flaws with this formula now that the trig functions are set to radians?
