Question

what is the period of 1/(2+sinx)? and how do you get it?

Answer 1

ok, just a second

Answer 2

i think its 2pi

Answer 3

just shifted to the left by pi compared to the sinx function

Answer 4

yes, there is that as well, but period doesnt matter about vertical shifts correct?

Answer 5

oh, i meant 1/(2+sinx)

Answer 6

oh... that changes things....

Answer 7

sorry :(

Answer 8

one second....

Answer 9

do you know calculus?

Answer 10

yes, this is for my partial differential equations class

Answer 11

all the way past calc 3

Answer 12

because the only way i can think of finding the period is to find the maximum of the function and figure out the distance from each maximum...

Answer 13

***between maximums..

Answer 14

can i do that on a calculator??? or...

Answer 15

ok.... \(\large f(x) = \frac{1}{2+sinx} \)

Answer 16

yup

Answer 17

on a calculator, sure you can.....

Answer 18

you wanna just do it with calculator instead of finding the maximums?

Answer 19

with calculus?

Answer 20

nope, calc is better

Answer 21

ok... hang on a sec...

Answer 22

this is the online calculator i'm using:
https://www.desmos.com/calculator
it finds the "points of interests" meaning the max/mins.. here's a screen shot...

Answer 23

ok, that is much clearer than my calculator

Answer 24

putting my cursor on the two adjacent maximums gives x=-pi/2 and x=3pi/2 as the x coordinates of the maximums.

Answer 25

so 2pi

Answer 26

haha... yep....

Answer 27

i was afraid you wanted to take derivatives! :)

Answer 28

lol, i attached the wrong one!!!!!!

Answer 29

oh wow .... thanks for the bank account number... :)

Answer 30

kidding!

Answer 31

yeah, no problem!!!! i know you are just itching to do my mathlab hw!

Answer 32

awww , i thought i could enjoy more math problems to take me through the night!

Answer 33

lol, i got another....

Answer 34

ok... couldu make a new post ? thnks....:)

Answer 35

yup
