Homework Statement
Standing on the ground 3.0m from the wall of a building you want to throw a package from your 1.5m shoulder level to someone in a second-floor window 4.2m above the ground. At what speed and angle should you throw the package so it just barely reaches the window...
So I have this Class Random that needs to have a friend function sort which needs to exist in two namespaces.
Class Random
{
... Some stuff
friend void sort(Random &x);
}
namespace ascending
{
void sord(Random &x)
{
... Some Stuff
}
}...
Homework Statement
f(x) = x - \sqrt{x}Homework Equations
f'(x) = \lim_{h \to 0} \frac{f(a+h)-f(a)}{h}The Attempt at a Solution
I'm not exactly sure how to solve this problem. I plugged the problem into the equation and got stuck... I have a class right now, so I'll have to post my work later.
My professor just shows
a) f(a) must be defined
b) \lim_{x \to a} f(x) must exist
c) \lim_{x \to a} f(x) = f(a)
I looked in my book and the section which uses the epsilon delta proof was skipped... He said it's to complicated to for us right now and will come back to it at the end of...
Homework Statement
Find the equation of the tangent line to the curve at the given point.
y = \sqrt{2x+1} , (4, 3)Homework Equations
a = 4
M =\lim_{x \to a} \frac{f(x) - f(a)}{x-a}
or
Mpq = \lim_{h \to 0} \frac{f(a+h) - f(a)}{h}
The Attempt at a Solution
M =\lim_{x \to 4} \frac{f(x) -...
It's not so much the symbols or the concepts that are hard, it's the explanation... I'm trying to understand my professors Korean-English while attempting comprehend the course work. He's a nice guy and I don't mind him as a teacher. But sometimes his explanation is more confusing than the...
I'm currently using Stewart "Calculus" 5th ed, Brooks/Cole. I dont' know if we get to epsilon delta proofs further along in the book, but for now they aren't discussed in any of the chapters that have been assigned.
