sec x = 1 / 12/13
sec x = 1 * 13/12
sec x = 13/12
sen²x + cos²x = 1
sen²x + (12/13)² = 1
sen²x +144/169) = 1
sen²x = 1 -144/169
sen²x = 25/169
sen x = raiz de 25/169
sen x = 5/13
cossec x = 1 / 5/13
cossec x = 1*13/5
cossec x = 13/5
sec x = 1 * 13/12
sec x = 13/12
sen²x + cos²x = 1
sen²x + (12/13)² = 1
sen²x +144/169) = 1
sen²x = 1 -144/169
sen²x = 25/169
sen x = raiz de 25/169
sen x = 5/13
cossec x = 1 / 5/13
cossec x = 1*13/5
cossec x = 13/5
