Question

What? <:/

Answer 1

plug in t=6 and what do you get?

Answer 2

Well I know to plug in 6 where t is but i don't know how to solve

Answer 3

what it's basically saying is y(t) is the height that your spring is moving and it's asking what is the displacement, y(t) when t=6 aka y(6)

Answer 4

simplify it

6*pi 2pi/6 = 12pi/6 which = 2pi so now you have

\[9.6cos(2\pi-\frac{\pi}{2})\]

Answer 5

\[9.6cos(\frac{4\pi}{2}-\frac{\pi}{2})=9.6cos(\frac{3\pi}{2})\]

Answer 6

where'd you get 6pi? if you don't mind me asking (:

Answer 7

i meant 6*2pi/6

Answer 8

oh, alright I see (:

Answer 9

cos at 3pi over 2 is.....

Answer 10

30 degrees?

Answer 11

and 330 degrees

Answer 12

to find out how much it is in degrees use

\[3\pi/2*\frac{180}{\pi}\]

Answer 13

270?

Answer 14

yep and 270 is 3 90 degree turns so you get this
