Hello, I am in need of some assistance from someone smarter than me. Haha.
HELP please

How do I back calculate to “f”?
? = (L * ?c) / (? * ? * P)
Where:
? = 1.0366
L = 1000
? = 5.8E+08
P = 12.56
?c = (1+(2/ ?)*ATAN(1.4*(?/ ?)^2))
? = 0.07874
? = (1/SQRT(? *f* ? * ?))*39370.07874
? = 1.257E-06
I can solve for f once I figure out how to calculate ? and ?c. So basically I have two unknowns. I am having a hard time trying to figure this out. “f” should work out to approx 1E+09
My second problem to calculate is for ?
? = (L * ?c) / (? * ? * P)
Where:
? = 1.0366
L = 1000
f = 1E+09
P = 12.56
?c = (1+(2/ ?)*ATAN(1.4*(?/ ?)^2))
? = 0.07874
? = (1/SQRT(? *f* ? * ?))*39370.07874
? = 1.257E-06
So in this problem, I need ? to be able to solve for ? and ?c. So there are 3 unknowns here. ? should work out to be about 5.8E+08.
These are obviously a little over my head here. I am tasked to create a program for work… I can code it, just not sure how to solve it. Similar to above, I have no problem solving this if I know all but one unknown.
Thank you for your assistance.
