Hey guys I was just taking a look at a sample exam and I came across this, with no recollection of ever learning it.
I don't really want anyone to solve a problem for me per se, I just want an explanation for what is being asked.
So anyway, I am asked to find the linear estimate for a...
Yeah, I understand what you're saying, but I'm still stuck.
I guess I'll show you my work.
(n-2)!(n+1)!/(n!)²
= (n-2)(n-1)n!(n+1)!/n(n-1)(n-2)!(n!)
= (n+1)!/n!
What I have trouble with is I guess why the answer is (n+1)/n(n-1). Can I not just cancel out the factorial symbol...
Hey, I was wondering if someone could help me with a specific type of question that I can't seem to understand without an answer key. Anyway, it's rewriting expressions with factorial notation so that they no longer have factorial symbols.
Example:
Simplify without using the factorial...
Yeah, thanks a bunch x, I've figured out that question. However, I have a few other questions. This regards a ferris wheel problem I'm working with.
Ferris wheel:
Diameter: 76m
Maximum Height: 80m
Ferris wheel has 36 carts, which each cart able to hold approximately 60 people.
It rotates...
That actually helps me a lot, but rather than drawing a cosine graph, I drew a sine graph. Thanks a bunch x.
I've come up with an equation, but I'm not sure how right I am, if someone could verify, that would be great.
y=1.25sin(π)x+1.75
The thing in the brackets is pi, sorry, but I...
I'm having some trouble with applying trigonometric functions to some real life situations, particularly this one problem in my homework.
Andrea, a local gymnast, is doing timed bounces on a trampoline. The trampoline mat is 1 meter above ground level. When she bounces up, her feet reach a...
