Hi guys!
I've been trying to solve a math problem in excel but I guess I've forgotten math a lot over the years.
I've got the formula:
A = 2*DEGREES(ATAN(43,3/(2*X)))
where A is the Field of View angle of a 35mm camera with focal length X. I need to covert the formula to do the opposite and calculate X with known A. But I cannot use Goal Seek as I need this as a formula. Can anyone help me to convert the formula?
Thanks!
