escriba cada expresion en terminos de la que se indica:
a.TAN B en terminos de SEN B
b.SEN B en terminos de SEC ala 2 B
c.CSC B en terminos de COS ala 2 B
d.CTG en terminos de CSC B

Tan B= sen b/cos b= sen b/ raiz cuadrada de (1-sen a la 2 b)
sen b = raiz de (1- cos^2 b)=raiz de (1-(1/sec^2 b))
csc b= 1/sen b = 1/ raiz de (1-cos^2 b)
ctg b =cos b /sen b= raiz de (1-(1/sec^2 b)) / (1/csc b)
