Question

if cos theta = 0.5, find sec theta.

0.25 <---
0.5
1
2

Answer 1

what is secant?

Answer 2

the ratio of the hypotenuse to the shorter side adjacent to an acute angle. right?

Answer 3

kinda. in that cos = adj/hyp
sec = hyp/adj

secant is 1/cos

Answer 4

so if \(cos(\theta)=\frac{5}{3}\)
\(\huge sec(\theta)=\frac{1}{\frac{5}{3}}=\frac{3}{5}\)

Answer 5

3/5 comes out to 0.6, but 0.6 isn't in my choices.

Answer 6

my head hurts

Answer 7

I made up an example to demonstrate the concept

Answer 8

if cos = .5
sec = 1/0.5=\(\large \frac{1}{\frac{1}{2}}=\frac{1}{}*\frac{2}{1}=2\)

Answer 9

cos (theta)=1/sec(theta)

Answer 10

1/2=1/(1/2)=2
