Question

Can someone please help me with this trigonometry question?

Answer 1

@just_one_last_goodbye maybe?

Answer 2

I dont like your username .-.

Answer 3

so you wont help me because you don't like my username?

Answer 4

What can you deduce from this picture to help you answer?

Answer 5

Let me explain: What the picture demonstrates is... sin a/cos a = tan a

Answer 6

Your equation essentially shows this: sin a sin b/cos a cos b = ?

Answer 7

i can deduce that cosecant relates with sine and secant relates with cosine

Answer 8

Simplified: tan a = sin a/cos a

What do you think?

Answer 9

The difference between your equation and (tan a = sin a/cos a) this one is that your has sin b/cos b

Answer 10

sin(a + β) / (cos(a) cos(β)) = tan a + tan b

Answer 11

Yes! I was afk

Answer 12

thanks for your help!
