I re...First of all good job on the detailed answer. I really like how you put a lot of space so your solution will be easy to follow.After doing the whole question myself, I therefore conclude that Zeph's answer is the right one. There is something wrong with the algebra. There are many different ways to check this problem. One of them is to use your calculator. First of all, you need to plug in the function. Then press the 2ND button then TRACE then press 1.After that plug in your answer as the x value then press ENTER. You should see that the y value should be very close to 4. Thats the quick way of doing it.<BR/><BR/>-m@rkm@rkhttps://www.blogger.com/profile/00509544958003356512noreply@blogger.comtag:blogger.com,1999:blog-1000693476051168456.post-14623866886459754092008-03-13T20:08:00.000-05:002008-03-13T20:08:00.000-05:00yes yes part d is kinda confusing.

Since after I tried it, I ended up getting the same answer that Joseph has shown. Other than that, everything is good. Be careful of the order in which you solve those types of questions next time, okay? :Pkristinahttps://www.blogger.com/profile/12365815325056314375noreply@blogger.comtag:blogger.com,1999:blog-1000693476051168456.post-27754139160017880642008-03-13T17:49:00.000-05:002008-03-13T17:49:00.000-05:00This comment has been removed by the author.zephhttps://www.blogger.com/profile/14129231104888254698noreply@blogger.comtag:blogger.com,1999:blog-1000693476051168456.post-2951941932078324232008-03-13T17:47:00.000-05:002008-03-13T17:47:00.000-05:004 = 2.5 sin [2pi(t-1.5)/12.4] + 4.3Let X = 2pi(t-1...4 = 2.5 sin [2pi(t-1.5)/12.4] + 4.3<BR/>Let X = 2pi(t-1.5)/12.4.<BR/>4 = 2.5 sin X + 4.3<BR/>-0.12 = sin X <BR/>-0.1203 = X<BR/>-0.1203 = 2pi(t-1.5)/12.4<BR/>[(-0.1203)(12.4)/(2pi)] + 1.5 = t<BR/>1.2626 = t<BR/><BR/>...which converts to 1:15:45 a.m.zephhttps://www.blogger.com/profile/14129231104888254698noreply@blogger.comtag:blogger.com,1999:blog-1000693476051168456.post-10232260775659930102008-03-13T17:32:00.000-05:002008-03-13T17:32:00.000-05:00In your part D, I don't understand why'd you 'get ...In your part D, I don't understand why'd you 'get rid of' your phase shift before you divided the 2.5 on both sides.zephhttps://www.blogger.com/profile/14129231104888254698noreply@blogger.comtag:blogger.com,1999:blog-1000693476051168456.post-12475837246292352812008-03-13T16:59:00.000-05:002008-03-13T16:59:00.000-05:00welll, it's not that bad... it's quite understanda...welll, it's not that bad... it's quite understandable.. it's just if you want perfection, you know. but then again i wouldn't know about much of that. haha its just the "get rid of" that bothers me..:.
