have I done my radiant math wrong? I cant remember if you just 14tt÷180= radiant or is there a step I've missed?

Can you please state the original question more clearly? What is on the numerator on the RHS?

The conversion factor to remember:

You appear to have replaced $$\displaystyle \tan(\phi)$$ with 14°; that makes no sense, as the value of a tangent is a dimensionless number (ratio), not an angle in degrees or radians. Furthermore, you can't just replace a quantity in one unit with its value in another unit (14° with 0.2).
