$$ \frac{\sec 8 A-1}{\sec 4 A-1}=\frac{\tan 8 A}{\tan 2 A} $$

We are going to do problem number 37. And this question we need to find the value of the given expression. So let us start solving this question. No. What we need to do is we need to just find the value of sign 98° 10 minutes. So if we just see the value by tapping it on calculator then we will be getting This is 0.9899. Now moving to next question be part that has cost 603.7°.. So in this question again we have to do the same thing. So we will be getting zero 10979. See the change here is in the unit that her three is ingredients. So we'll be writing here that 10 3 then the value which we will be having is 0.14 25 No moving to depart in department to find court 231° 40 minutes. Okay so again typing this value then we will be having 0.7907. Now depart sake function as sick as the receivable of course. So we can type one divided by cost and then this value 1175. Okay, So we will be having manus 11.24 main tree. Okay. Now f Yeah this is ingredient than uh If we take this value on the calculator then we will be having 1.3677 is the answer. These are the answer in this case. That's all. Thank you.

So for this one, it says that the tangent of data is six over negative eight, which means that we have it in either the second or the fourth quadrant. Because that's the case in which tanginess negative. So then let's just put it in the second quadrant for now. So tangent out of So, uh, to, uh is the toe, uh, which means a tangent is opposite over a Jason. So the opposite is night of six, or we can call it six or negative six. Doesn't matter. And was so that's call theater J since negative eight. Because this data is the one that's gonna be closest to the origin stuffs angle we're looking at. So then, if we're looking for the coastline of that value, well, you can see that this is actually just gonna be a 345 triangle, cause this is three times to this is four times to. So this right here, the hypotheses must be five times juice about. We'll call that 10. So that means that we have to have, um, this situation of co sign so co sign of data. What coastline is cup? So C is a over h so adjacent is negative. Eight and high pot news is 10. We have negative 8/10. So are correct. Answer here should be see?

Were given a substitution. X is equal to eight seeking data and asked to express the change it of Fada in terms of x so x equal eight secret that that means that X over eight is equal to the seeking of data. So if I draw this out and a right triangle, here's my angle data with Seek It is the reciprocal of the co sign. So if the seeking is X over eight, that tells me that I have X and eight in this position. The remaining side of this triangle is X squared, Um, minus 64. So what is the tangent of that angle failure that you see there? The changing is the opposite over the adjacent, so that's just going to be square root of X squared minus 64 over eight.

A worker sequentially works on jobs. Each time a job is completed, a new one is begun. Each job, indcpendently, takes a random amount of time having distribution $F$ to complete. However, independently of this, shocks occur according to a Poisson process with rate $lambda$. Whenever a shock occurs, the worker discontinues working on the present job and starts a new one. In the long run, at what rate are jobs completed?
