Answer 2

21. Determine the quadrant when the terminal side of the angle lies according to the following conditions: cos (t) > 0, tan (t) > 0.

Quadrant IV
Quadrant I
Quadrant II
Quadrant III

Answer 3

oh nvm its not triangles i thought it was for some reason

Answer 4

ok remember (x,y)=(cos(theta),sin(theta)) (assume r=1)
you are given so for that x is positive
and y/x is positive
so what does that mean about y?

Answer 5

come on if you divide a positive by a positive you get a ?
and if you divide a positive by a negative you get a ?
and if you divide a negative by a positive you get a?
and if you divide a negative by a negative you get a ?

Answer 6

hint:

Answer 7

ok

Answer 8

the first quadrant?

Answer 9

yes since y/x is positive and x is positive
then yes y is definitely positive also

Answer 10

so you have (x,y)=(+,+)

Answer 11

so its in quadrant 1?

Answer 12

yes is what I said :p

Answer 13

hehe sorry

Answer 14

ok @freckles and @Michele_Laino \[Given \cot \theta=\frac{ 3 }{ 10 } find \tan \theta\]

Answer 15

i tried this and couldn't find it

Answer 16

this is the last one

Answer 17

tan and cot are reciprocal functions of one another

Answer 18

it is very simple, since we have:
\[\tan \theta = \frac{1}{{\cot \theta }} = \frac{1}{{\frac{3}{{10}}}} = 1 \times \frac{{10}}{3} = ...?\]
since we have to compute the first fraction by the inverse of the fraction at denominator

Answer 19

i got 3.3 lol

Answer 20

better is to express the result as a fraction
