Question

Help with two questions? http://prntscr.com/3l2f6h

Answer 1

hint : \(\sec \theta = \frac{1}{\cos \theta}\)

Answer 2

hehe

Answer 3

I honestly have no idea how to do this my teacher doesnt teach me these things :|

Answer 4

Remember your trig ratios and triangles?

Answer 5

these are extension to SOH-CAH-TOA

Answer 6

Using ganeshies hint we have

\[\frac{ 1 }{ \cos \theta } \times \cos \theta =~?\]

Answer 7

just 1 then?

Answer 8

Yup

Answer 9

because cosθ cancels out right?

Answer 10

\[\csc \theta = \frac{ hyp }{ opp }\]

\[\sec \theta = \frac{ hyp }{ adj }\]

\[\cot \theta = \frac{ adj }{ opp }\]

Answer 11

\[\frac{ 1 }{ \cos \theta } \times \cos \theta = ~ \frac{ \cos \theta }{ \cos \theta } \implies 1\]

Answer 12

Just a heads up \[\cos ^{-1} x \neq \frac{ 1 }{ \cos x }\]

I see people mess that kind of stuff up all the time.

Answer 13

Ok i will try not to mess that one up o.o but how does that help me answer my question?

Answer 14

It doesn't lol, just letting you know, anyways have you attempted the second question?

Answer 15

Sadly no, because like i said earlier i have no idea how to do this. I havent even tried the first :\
