Question

Simplify sec(theta)cos(theta)?

Answer 1

R U taking the unit quiz for chapter 14?

Answer 2

I'm on the same quiz!!!

Answer 3

sec(theta) = 1/costheta

so, just multiply (1/costheta)*costetha = 1

Answer 4

We would except we don't have calcs that do that

Answer 5

my options are:
tan theta
1
cot theta
cos theta
so it's 1?

Answer 6

O! nevermind, Can you help me with my questions, it's the one under hers?

Answer 7

osmium i have a calculator..

Answer 14

I don't have a calc. I'm trying to learn how to do these without a calc and that is pretty much impossible. Sorry, jeez.

Answer 15

I will use latex to make it easy to see:\[\sec \theta = \frac{ 1 }{ \cos \theta }\]It's a rule. So,\[\sec \theta*\cos \theta=\frac{ 1 }{ \cos \theta } * \cos \theta = \frac{ \cos \theta }{ \cos \theta } = 1\]

Answer 16

I remember that now thanks.
