Answer 2

what do you need help on?

Answer 3

I took a screenshot of the problem

Answer 4

Can you attach it ,so I can see the problem?

Answer 5

For what value(s) of t, with 0 ≤ t ≤ 4, is the slope of the curve undefined for the graph defined by x = 2t – 2 sin(t), y = 2 – 2 cos(t) ?

Type your answer in the space below to the nearest whole number. (ex: 4)

Answer 6

so i found dy dx which is (sint)/(2-cos(t)

Answer 7

I dont think it can be undefined

Answer 8

yes, I couldn't find anything about it.

Answer 9

do you know anybody that could help potentially?

Answer 10

i think you are missing some 2's

Answer 11

On my derivative?

Answer 12

yep

Answer 13

yeah just noticed

Answer 14

(2sint)/(2-2cos(t)

Answer 15

so anyways we solve dx/dt=0

or 2-2 cos(t)=0

Answer 16

equivalent to solving cos(t)=1

Answer 17

this can happen unlike your previous equation where you had 2-cos(t)=0 since cos(t) is never 2 because cos(t) can only be a number between -1 and 1 (inclusive)

Answer 18

so t=0 is that answer

Answer 19

I was getting so frustrated because I could not figure out why i couldnt get dx/dt to equal 0. Forgot some 2's lol

Answer 20

it happens

Answer 21

to all of us

Answer 22

thank you :)
