La expresión

 sec2 = tan2 + sen2\sec^2\ =\ \tan^2\ +\ sen^2 tiene un error, la identidad verdadera es:

 sec2 =tan2 + 1\sec^2\ =\tan^2\ +\ 1  

 sec2 = 1 + cot2\sec^2\ =\ 1\ +\ \cot^2  

 sec2 = tan2  1\sec^2\ =\ \tan^2\ -\ 1  

 sec2 =tan2  sen2\sec^2\ =\tan^2\ -\ sen^2

La expresión

 x = 1tan xx\ =\ \frac{1}{\tan\ x}  esta incompleta, la identidad verdadera que la completa es:

 cot x = 1tan x\cot\ x\ =\ \frac{1}{\tan\ x}  

 cos x= 1tan x\cos\ x=\ \frac{1}{\tan\ x}  

 cot x =cos xsen x\cot\ x\ =\frac{\cos\ x}{sen\ x}  

 cot x × tan x = 1\cot\ x\ \times\ \tan\ x\ =\ 1
