# Can someone help me solve this? tan s is over 1+cos s + sin s is over 1-cos s = cot s + sec s csc S?

Its about Verifying Trigonometric functions & that's the last # I need to. But I just can't get the right solution.. :/

tried doing it fancy by typing it on word first but it didn't work :( oh well, you're just gonna have a hard time deciphering it ;P

tan s/(1+cos s )+ sin s/(1-cos s )=cot s+(sec s x csc s)

LHS = tan s/(1+cos s )+ sin s/(1-cos s )

(tan s(1-cos s)+sin s(1+cos s) )/(1- cos^2 s )

(tan s - sin s + sin s + (cos s x sin s) )/sin^2 s

(tan s + (cos s x sin s) )/sin^2 s

1/(sin s x cos s) + cos s/sin s

(sec s x csc s) + cot s
