Question

Reducir:
SENX /1+COSX +1+COX / SENX

Answer 1

Sen(x)/(1+cos(x))+(1+cos(x))/sen(x)= (sen^2(x)+1+2cos(x)+cos^2(x))/(sen(x)(1+cos(x))

sen(x)/(1+cos(x))+(1+cos(x))/sen(x)=(2+2cos(x))/(sen(x)(1+cos(x))

sen(x)/(1+cos(x))+(1+cos(x))/sen(x)=2(1+cos(x))/(sen(x)(1+cos(x))

sen(x)/(1+cos(x))+(1+cos(x))/sen(x)=2/sen(x) 

sen(x)/(1+cos(x))+(1+cos(x))/sen(x)=2csc(x)
