Question

Complete the identity

Answer 1

\[\frac{ \cos(\alpha-\beta) }{\cos \alpha \cos \beta }\]

Answer 2

\[\frac{ \cos(a)\cos(b) + \sin(a)\sin(b) }{ \cos(a)\cos(b) }\]
\[\tan(a)\tan(b)\]

Is this it? or can someone else simplify it further?...

Answer 3

well @greenleaf800073 these are the answers
A. 1 + cot α cot β

B. tan α tan β + cot β

C. 1 + tan α tan β

D. 1 + cot α tan β

Answer 4

@jim_thompson5910 @Hero ??

Answer 5

AH, WOOPS

It's C

hehe, forgot to add the 1 +

Answer 6

okay thanks @greenleaf800073 i got one more of these could you help?

Answer 7

sure

Answer 8

\[\frac{ \sin(\alpha +\beta) }{ \cos \alpha \cos \beta }\]

Answer 9

A. cot α + cot β

B. tan α + tan β

C. tan β + tan α

D. -tan α + cot β

Answer 10

@greenleaf800073 ???

Answer 11

\[\frac{ \sin(a)\cos(b) + \cos(a)\sin(b) }{ \cos(a)\cos(b) }\]
\[tan(a) + tan(b)\]

I'm only 90% sure on this answer, anyone want to reassure?

Answer 12

i'll just try it and let ya know (:
