Question

Will give medal! Please help~

Find the remaining trigonometric ratios.
tan(a)=2,0 < a < pi/2

sin(a)=
cot(a)=
csc(a)=
cos(a)=
sec(a)=

Answer 1

Where are you stuck?

Answer 2

use

tan = sin /cos

Answer 3

do you know what mean csc and sec ? and csc = ? and sec = ?

Answer 4

@jhonyy9 @Loser66 I know what each individual ratio is (csc=1/sin, etc.), but I just don't know how to go about solving the problem :(

Answer 5

i ve wrote above that

tan = sin / cos

use this

Answer 6

@jhonyy9 , so... I still don't understand what tan would be. Would it be 2?

Answer 7

@jhonyy9 if it is 2, then sin/cos = 2/1... but the answer said that sin does not equal 2

Answer 8

sin
---- = 2
cos

this not is equivalent with

sin 2
--- = ---- and from this result than sin = 2 and cos = 1
cos 1

hope you understand it now

Answer 9

and hope you know that cot = 1/tan

Answer 10

But the answer said that sin doesn't equal 2 @jhonyy9

Answer 11

I'm still confused lol

Answer 12

yes this i right sin not equal 2 bc. sin/cos = 2

Answer 13

sin 2
--- = ---- cross multiply and will get sin = 2cos
cos 1

Answer 14

so... sin=2cos... But you don't know what cos is? @jhonyy9

Answer 15

nvm I figured it out lol but your answer didn't help at all

Answer 16

just you need using your knowledge from trigonometry - yes ?

Answer 17

for example

cot = 1/tan so cot = 1/2

yes ?

Answer 18

mhm

Answer 19

@OtherWorldly something about this please ?

Answer 20

i don't know trigonometry sorry :(

Answer 21

haven't gotten to that point yet

Answer 22

@jackthegreatest pretty sure u would know this

Answer 23

yep i would
