Ok, ill try to explain what i did:
1.
integral of [square root of( e^t-3)dt]
Sorry i didn't know how to do the square roots symbol and the integral symbol. Anyways, I tried to set e^t-3 as u and then got dt=du/e^t. Then I plugged in dt and couldn't go on after that.
2. integral of...
Yes, I realize its integration by parts. I've been doing other problems with the product rule. Its just these that I'm stumped on. I basically don't know where to begin with some of these.
for this one: integral of (lnx)/(x^2) dx , are you supposed to change it to (lnx)(x^-2) first and then...
There are several situations I don't know how to solve:
integral of (lnx)/(x^2) dx
integral of e^x(cos2x)dx
integral of ln(1+x^2)dx
I have a quiz tommorow, and after looking through some notes, this is what I couldn't understand.
Please help! thanks.
Help on continuity!
1) Ok, i know how to find x, but how do you know if something is nonremovable or removable discontinuity?
like for this:
f(x)=|x+2|/(x+2)
i knoe its x=-2, but is it nonremovable or removable?
2) How do u do the continuity stuff with there:
f(x)=csc2x...
limits help!
ok I am going to try my best to express these problems because I don't really know how to get some of these symbols. If someone knows how to represent these:
infinity
radical
please tell me.
On to the problems (we need to find the limit):
1)
lim x / radical(x^2-x)...
quiky question before my test tommorow morning!
i can't believe i duno where to find out how to do this:
1) find intersections of the graphs:
x^2+y^2=41
x+2y=6
and
2)which of the following function is equivalent to the following piece function.
x-3, if x>=3
f(x)={...
ok I am still confused about one part in number 6. How did you go from 0 = log[2](x-1)^2 to 1 = (x-1)^2 ? How did the log[2] disappear? WHered the 1 come from?
And also one more thing, you said to know the graph of the th general log functions.
for this: f(x) = log[n]x, how can i...
Allright, I have a math test next week and there's some things i want to clear up before i take it. I can't use a calculator btw.
1) We've learned a lot about testing symmetry (y-axis, x-axis, origin). It seems on most problems we just test y and origin symm. When do you know you shoudl test...
OK, i still have some issues with each of these, and like i said, i my teacher hasnt explained any of these yet.
66. So i assume u mean to find the equation for the line p and h right? But how do you do that? how do u find the equation between that point on the curved line and the x-axis...
