We want to find the temperature for a particular city given what day of the year it is.
00:06
And they want to do this for may 5th, which is day 125.
00:09
They tell us that.
00:11
So we need to find t of 125.
00:13
Then they tell us they want us to know for december 14th.
00:16
But we have to figure out what day of the year that is.
00:19
So we know that december the 31st is day 365.
00:24
Well, how many days left in the year from that? well, so when we subtract that, that's going to be 7 .5.
00:30
Days that are going to be remaining.
00:32
So when we subtract 17 from here, we're going to get 348.
00:39
So that's going to be t of 348.
00:42
December 14th would be the 348th, the 4th, 348th day of the year.
00:47
So we're going to take these values, and we're going to put them in place of our expression.
00:52
Now make sure that when you're doing this, that we have your calculator in radian mode, because i'm looking at my values being, in radiance, and i know that because of the pi...
