OpenStudy (anonymous):

ok, use a calculator!

OpenStudy (anonymous):

if i knew i wouldnt ask...

OpenStudy (anonymous):

it says "use a calculator" so there is nothing really to know

OpenStudy (anonymous):

not rlly in the mood for you to show how stupid i am, idk wat to press to get the answer

OpenStudy (anonymous):

plug "cos(63.1) " in to a calculator and read what it says you are not supposed to be able to figure this out somehow,

OpenStudy (anonymous):

depends on the calculator which one are you using?

OpenStudy (anonymous):

computer calculator

OpenStudy (anonymous):

actually, you don't even need one since you are on a computer just type "cos(63.1)" here http://www.wolframalpha.com/

OpenStudy (anonymous):

you should get this http://www.wolframalpha.com/input/?i=cos%2863.1%29

OpenStudy (anonymous):

after tht do i just move the decimal to the right 4 times?

OpenStudy (anonymous):

no!

OpenStudy (anonymous):

just read off what it says

OpenStudy (anonymous):

round to four decimal places means include for decimal places

OpenStudy (anonymous):

wt does tht mean

OpenStudy (anonymous):

it means write the number down you see, stop after the 4th digit

OpenStudy (anonymous):

what number do you see?

OpenStudy (anonymous):

4524

OpenStudy (anonymous):

you forgot to write the decimal point i think

OpenStudy (anonymous):

4524.

OpenStudy (anonymous):

lol no

OpenStudy (anonymous):

idk bro

OpenStudy (anonymous):

it says \(\large.4524\)

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

in sine and cosine are always numbers between -1 and 1

OpenStudy (anonymous):

that is the answer

OpenStudy (anonymous):

wat about rounding to 4th decimal place

OpenStudy (anonymous):

\(\huge .4524^{\text{4th decimal place here}}\)

OpenStudy (anonymous):

?

OpenStudy (anonymous):

\(.45243\) five decimal places

OpenStudy (anonymous):

ok got it

OpenStudy (anonymous):

\(.452435\) five decimal places

OpenStudy (anonymous):

since the answer is a non repeating, not terminating decimal, they are just saying "after for places, stop writing anything"

OpenStudy (anonymous):

ok
