Question

Graph y = cosx for - ≤ x ≤ -.

What is the largest value in the range?



-1

0



1

Answer 1

do you know the unit circle?

Answer 2

yes

Answer 3

so on the unit circle, what values does the x-value stay between?

Answer 4

or you don't know that
do you believe in any right triangle the hyp is always the biggest?

Answer 5

idk im on odyssyware the unit circle not on here

Answer 7

wouldnt the answer be 1 ?

Answer 8

yes the range of both y=sin(x) and y=cos(x) is [-1,1]
These values on the unit circle for x and y stay between -1 and 1 (inclusion)
so the max value for either is 1

Answer 9

thank youuu so much

Answer 10

Which of the following ordered pairs lies on the graph of y = tanx?



(-, -1)

(-, 1)

(, )

(5π, 0)

Answer 11

Which of the following ordered pairs lies on the graph of y = tanx?



(-, -1)

(-, 1)

(, )

(5π, 0)

Answer 12

I only see one pair of numbers so I would try to see if that one pair works.

Answer 13

\[0=\tan(5 \pi)=\frac{\sin(5\pi)}{\cos(5\pi)}\]

Answer 14

you want to see if that equality holds

Answer 15

if it holds then (5pi,0) is a point on y=tan(x)

Answer 16

and I guess your question before you were actually given the range you just didn't type any of the numbers ?
