## Question #2

(%/100)/2pi = your answer (which is negative)

Note** pi = 3.14

For example: Percentage given = 30.86

.3086/(2*3.14)=0.049115 (answer is negative)

Note** pi = 3.14

For example: Percentage given = 30.86

.3086/(2*3.14)=0.049115 (answer is negative)

## Q3

Hey, im glad i can actually help because usually when i come here the answers are already posted.

q3 is simply:

#turns/factor ( second number in the question/first)

answer is positive

glad i can help and thanks to everyone who constantly helps the rest of us out

## Re: Maple TA 19_2

for 19-2 #2

its sin inverse of % say .8990 and then divide that # by 2*pi and the answer is negative

make sure ur calculators r in radian, weird but works

## question 2

I don't understand question 2. I have 57.65 as my percentage.

I am doing .5765/2*pi, and getting 0.092. Its incorrect. what am i doing wrong???

thanks!!!

This worked for me:

inverse sin( 87.37/100)= 1.06275703

take that answer / (2pi) = .1691430346.

inverse sin( 87.37/100)= 1.06275703

take that answer / (2pi) = .1691430346.

## Q 2

Hey...i tried that answer, but it didn't work. where are you getting the number that you are taking the inverse sin of?

**helpme2**- Guest

## #2

Hey great work mer...1 and gr8luck. I have no idea how you got this one. my%was 63.1 so..

sin^-1(0.631) then divide that by 2*pi. That should work. good luck on the exam all!!

OH GREAT GOD OF PHYSICS HERE MY PRAYER. AND HAIL TO THE ANGELS OF PARTIAL CREDIT.

## radian mode?

how would we know if we had to switch to radian mode if they didnt tell us...? like on the test for example...

**guest123**- Guest

## radian mode

Thye told us to switch to Radian mode for question #2 and I am sure that they will tell us on the exams as well. When I approached the professor about when to use degrees/ radians he did tell me that radians are the SI unit so if nothing is given in degrees use radian mode to get the answer in radians and you should be okay. Hope this helps. Good luck on the exam on Monday everyone!
