Question

if rect(t) is function between -1/2 to 1/2

would rect(t/4) be stretched or shrunk?

Answer 1

why

Answer 2

lol btw what do you mean by stretch and shrunk?

Answer 3

ok if we take sinx and sinx/4 , it lies between -1 and 1

Answer 4

so i beliueve it wont change

Answer 5

it would stretch

Answer 6

Why?

Answer 7

ishaan, that's what I am thinking too

Answer 8

u=t/4

-1/2<u<1/2
-1/2<t/4<1/2

Answer 9

but u aren't provided with the function

Answer 10

It would stretch in the horizontal direction - not the vertical direction. @Akshay Budhkar is correct in that sense.

Answer 11

-2<t<2

Answer 12

I meant the period

Answer 13

-_-

Answer 14

the period stretches !

Answer 15

lol what else were you thinking? akshay

Answer 16

I think he was thinking amplitude

Answer 17

@imranmeah91 - there is nothing in the question to indicate that rect is a periodic function

Answer 18

oh amplitude

"if rect(t) is function between -1/2 to 1/2 "
i think this lines suggests it's periodic nature

Answer 19

line*

Answer 20

ok, horizontally stretched

Answer 21

one possibility is it could asymptote towards the two limits
