Answer 1

Heres the question!!!

Answer 2

do you know what the question is asking?

Answer 3

No

Answer 4

it is asking to find cos, sin, tan, sec, csc, cot

Answer 5

those are the six trigonometric ratios

Answer 6

Well can you help me figure them out?

Answer 7

so what is cos

Answer 8

I am not sure.

Answer 9

in a right triangle, weren't you taught that cos of angle = adjacent/hypotenuse
cos=adj/hyp

Answer 10

Oh yeah i remember now yeah.

Answer 11

so what is the adjacent side

Answer 12

Side X ??

Answer 13

there is no side x in your problem
the x the angle not the side

Answer 14

Oh ok i understand

Answer 15

we just said it adjacent/hypotenuse

Answer 16

so cosx=?

Answer 17

look at the triangle i drew and compare it to yours

Answer 18

Is it 3?

Answer 19

3 is just the adjacent
cosx=adj/hypo
so cosx=3/5

Answer 20

Oh ok

Answer 21

what about sin?

Answer 22

sinx= opposite/hypotenuse

Answer 23

sinX=4/5?

Answer 24

yes

Answer 25

Awesome thanks :)

Answer 26

now tanx=opposite/adjacent

Answer 27

no problem :)

Answer 28

tanX= 4/3?

Answer 29

good

Answer 30

secx=hypotenuse/adjacent

Answer 31

secX= 5/3?

Answer 32

good

Answer 33

cscx=hypotenuse/opposite

Answer 34

cscX=5/4?

Answer 35

yes

Answer 36

last one
cotx=adjacent/opposite

Answer 37

cotX= 3/4?

Answer 38

good

Answer 39

that's all :)

Answer 40

Can you help with this one?

Answer 41

you notice that sec and cos are reciprocal of one another
cos= adjacent/hypotenuse whereas sec=hypotenuse/adjacent
same goes for sin and csc
tan and cot

Answer 42

Ok cool so is that how i explain it on there?
