(tan x + cot x) / sec x = csc x

 

(tan x + 1/ tanx)/sec x= csc x

 

[(tan²x+1)/tanx]/ sec x = csc x

 

(sec²x/tanx)/ sec x = csc x

 

[(1/cos²x)/(senx/cosx)]/ sec x = csc x

 

(1/senx cosx) / sec x = csc x

 

(1/senx cosx)/(1/cosx)= csc x

 

cos x / sen x cos x = csc x

 

1/ senx  = csc x

 

csc x = csc x

 

 

ESPERO TE SIRVA

 

 

 

tan x + (cos x / sen x)/ (1/cos x)= csc x

 

tanx + cos²x/senx = csc x

 

senx / cosx + cos²x/senx = csc x
