Question

The function f(t) = 65 sin (π/5 t) +35 models the temperature of anperiodic chemical reaction where t represents time in hours. what are the maximum and minimum temperatures of the reaction, and how long does the entire cycle take?

Answer 1

A) maximum:65 degrees; minimum:35 degrees; period: pi/5 hours
B) maximum:100 degrees; minimum: -30 degrees; period: pi/5 hours
C) maximum: 65 degrees; minimum:35 degrees;period: 10 hours
D) maximum:100 degrees; minimum:-30 degrees; period:10 hours

Answer 2

do you know the max value of y=sin(x)?

Answer 3

No, I'm not sure how to find that.

Answer 4

have you ever graphed y=sin(x) before?

Answer 5

No

Answer 6

do you know what sin(0) and sin(pi/2) and sin(pi) and sin(3pi/2) and sin(2pi) equal?

Answer 7

I'm honestly just not sure where to even start with solving this question.

Answer 8

trying to give you a place to start
can you answer my last question please?

Answer 9

No, I don't know that

Answer 10

well that could be your problem and answering this
because you don't know anything about the function sin(x)

Answer 11

I don't know where to start now

Answer 12

can you give me a place to start?

Answer 13

like is there anything you know about trig?

Answer 14

like do you know the unit circle?

Answer 15

I know the basics of sin and things like that, but other than that, I haven't gone over trig for quite a while.

Answer 16

like what basics?

Answer 17

like knowing sin(0) and sin(pi/2) and so on are pretty basic

Answer 18

sin(0)=0
sin(pi/2)=1
sin(pi)=0
sin(3pi/2)=-1
sin(2pi)=0

so this doesn't look at all familiar?

Answer 19

It looks a bit familiar.

Answer 20

well using that information I'm able to graph the function y=sin(x) on [0,2pi]
