Answer»

-STEP EXPLANATION:ϘႮᎬՏͲᏆϴΝ:-SHOW that cos0/1+sin0=1-sin0/cos0ᎪΝՏᏔᎬᎡ:-LHS=sin0-cos0+1/sin0+cos0-1on DIVIDING by cos0 up and down,thentan0+se0-1/tan0-sec0+1= sec0+tan0-(sec20-tan20)/tan0-sec0+1= sec0+tan0-{(sec0+tan0)(sec0-tan0)}/tan0-sec0+1=sec0+tan0(1-sec0+tan0)/tan0-sec0+1=sec0+tan0*(sec0-tan0)/(sec0-tan0)=(sec20-tan20)/(sec0-tan0)=1/sec0-tan0)=RHS
