Hi I am sorry but I am not very good at math and don't know how to help you with this problem. The way that it is presented is kind of confusing to be honest. But I wish you the best of luck with it, have a good rest of your day. :)
so what is the problem?
its the document I have attached. I don't know another way to put the problem on here other than that
Well, the limit is 45, so are you asking for the limit or are you asking for something else?
the limit, I knew the answer to that one I just don't know how to work it out
ahh, just plug 3 into x and you get your limit.
limits are like substitutions in some ways. However, some limits are a bit more special.
for example 1/x-5 when x approaches 5. If it approached from the right side, it will go to infinite, if it approached from the left side, it will go to negative infinite.
Thank you so much!! Can you please help me with 2 more.
yea, sure I got time.
1.lim x ->4 1/x-3 2.lim x ->0 sin x^2/x
for the first question, is it 1/(x-3) or is it (1/x)-3
ok, plug in x=4, and your limit should come out.
the answer is 1
and I somehow got zero for the second one.
hm.... wait for a sec
i got 2. Did you use l'hospital's rule?
ok im lost what is that
basically, when the limit (the number you plug in) will result in 0/0 or infinite/infinite, the equation would equate to the derivative of the top and bottom. I'll get you a vid to show you how it works.
but on the video he got 1 as the answer
Nvm I just got it. Thank you so much
