How do I reverse this formula?

[excellover1]

Ive got the following formula in Excel:

=DEGREES(ACOS(SIN(RADIANS($B$3))*SIN(RADIANS(W2))+COS(RADIANS($B$3))*COS(RADIANS(W2))*COS(RADIANS(AF2))))

The values are:
$B$3=40.633
W2=-23.371
AF1=-177.339

to make it easier for you guys, this is the order it executes:

[1]. SIN(RADIANS($B$3))*SIN(RADIANS(W2))

[2]. COS(RADIANS($B$3))*COS(RADIANS(W2))

[3]. [2]*COS(RADIANS(AF2))

[4]. [1]*[3]

[5]. ACOS([4])

[6]. DEGREES([5])

Result (R): 162.59

Great.

I now want to rearrange the formula, to work backwards. How should the formula look if I want to put AF2 on the other side of the equals (and thereby making the result tell me AF2)? And how should it look if I want to put W2 on the other side of the equals?

Thanks in advance.

When I use that formula I get 64.004, and not 162.59. Are you sure that your formula and/or figures have been given correctly?
