$T=2\pi \sqrt{1/32}$

2. Directrix

What are the instructions?

3. miah

I have to replace T with these numbers 8 sec 6 sec 5 sec 6 sec 7 sec

4. miah

without the "sec"

@Directrix

6. Directrix

Are we supposed to get an exact answer or an aproximation?

7. miah

It doesnt matter

8. Directrix

If that is the case, then to what number does [2*π*√(1/32)] approximate? For each of the four problems, you can set that approximation equal to each of the 4 given values of T.

9. Directrix

What did you get? I have my approximation ready to reveal. In exact terms that product is the following: pi/[2√2]. But, we're doing approximations.

10. Directrix

Crank this out in your calculator: [2*π*√(1/32)]

11. miah

im so lost;/

In the following equation l stands for the length of the string in feet. Convert your 5 string lengths into feet by dividing by 12 (12 inches = 1 foot). Then, substitute each of these values into the given equation and solve for T (time for one period). Use 3.14 for π. Record these new measurements in the chart below. the number one above 32 is an "I"

I know you can approximate this: [2*π*√(1/32)] 2* 3.14159 * .17678 = ? @miah Multiply those numbers. You can use the calculator on your neck.

15. Directrix

If all else fails, go to Google.com and enter "2* 3.14159 * .17678=" in the search box.

16. miah

but its an "L" not a 1

17. Directrix

So, why are you just now saying that?

18. miah

I said it in the the message up there
