then
`v = a.^b`
now it's giving me the last one instead of the first one as the output
so [8]
instead of [2]
but not [2 4 8]
hmm I see, I'm at work now will have to check this out in a little while (unless someone else steps in π )
thanks for trying though, I do appreciate it
@Sam Southern - TN this works
The trick I had to remember was that a function that accepts scaler, if you plug in a vector, will return you a vector with the function applied to each entry
that, and making the vector 1...b is `1:b`
@ThisIsChris thank you, that works!
just got back from work, happy to see this finally work hahah
@Sam Southern - TN You're weclome! π
Whoever recommended Professor Leonard. Probably the best videos I've found for this. Much appreciated
@Deleted User that was @JC17-OR
@Deleted User My pleasure
I was wondering if someone could help me with a problem for my financial mathematics class?
<@&387091385075105804>
I'll go ahead and post a screenshot of the problem so people could see if they would be able to help.
@Deleted User What's the question? If you drop it here then when someone who can help comes on they can work on it
yeah perfect
Here are my notes. The example is supposed to align with how to do the problem, I just canβt seem to get the right answer.
Let me know if my notes can't be read.
I'm going to get some rest for tonight, but if anyone would still want to look at it and give me some guidance, I would greatly appreciate it. π
First, find future value:
FV = Principle\*(1 + rate\*time)
FV = 875*(1 + .1025 * 2)
FV = 1054.375
Then in one year there will be one year on the note left, and the bank is going to discount that at a 17.5% rate, so the discounted value the bank pays satisfies:
FV = DV * (1 + .175 * 1)
Plugging in the value for FV from before:
1054.375 = DV * (1.175)
Dividing both sides by 1.175 we get:
DV = 897.3404255319 = 897.34
So the holder of the note went from 875 to 897.34 in one year, so he has his own future value calculation he can plug values into:
897.34 = 875\*(1 + rate_for_holder \* 1)
dividing both sides by 875 you get:
1.0255314286 = 1 + rate_for_holder
so rate_for_holder = 0.0255314286... ~~ 0.026
so the rate for the holder is 2.6%
Thank you! @ThisIsChris I think I understand it much better now.
My pleasure! @Deleted User
Hey everyone I need some math help. I'm trying to do the final problem and I can't figure it out.
The best I've come up with is that the 2S-S argument only works for 2S -S, if you go above 2S-S to say 3S-2S, then it diverges to infinity. Also the r-value of 2 cannot be used in the geometric series sum equation as it is not between -1&1.
Any help is super appreciated.
If you talk about 3S you're just bringing more things in that you don't need.
when you do 2S-S you should have the same number of elements on both sides, or at least write it in the form of a sum
If you subtract these two sums, you should subtract the first from the first, the second from the second, etc.
So what you're saying is that the proof relies on ignoring standard rules of subtraction with equal terms.
