That damn t-formulae ! trig :( (1 Viewer)
- Thread starter Jaguar33

The t-results are actually the half angle formulae where t=tan (x/2).
1-tan^2(25)/1+tan^2(25) is actually expressed in the cos t-result form, which is 1-t^2/1+t^2.
Thus the answer is cos 50 because 1-tan^2(25)/1+tan^2(25) is just the t-result (half angle) of cos 50
Hope this helps
