well the definition of the derivative is
f(a+h) -f(a)
f'(a) = lim -------------
h->0 h
not sure how this helps me. Just having problems with this stuff. look through my notes and textbook and cannot find any problems like this.
Not sure how to...
Good Day
I have this limit question that I need to evaluate. I know the answer but am unsure how to answer it.
Evalualte:
lim (3^(x+1))(2-3^(-x))
x-> -Infinity
I know the answer is -3.
Any help would be great
Good Evening
I am studying for my exam next week and am not sure how to answer this question from one of my term test.
lim sin x / x represents the derivative of what function at what
x->0
number?
Does anybody know to do this?
thanks
Hello can someone point in the right direction on this one.
A particle moves along a strainght line with displacement s(t), velovity v(t), and acceleration a(t). Show that
a(t) = v(t) dv/ds
Explain the difference between the meanings of the derivatives dv/dt and dv/ds.
Does dv/dt...
all we have done with min or max is in the for of ax^2 + bx + c
if a < 0 then x= -(b)/2a is the max
if a > 0 then x= -(b)/2a is the min
this was a assignment and I got it wrong and think there will be something like it on the test. This is the only min max question we have had...
cool thank i will try to figure out where made the mistakes.
how do i figure out this part
For what value is of x is this total area a minimum
Thanks again
Yeah I should have seen that.
So now that I know that the height
h=\frac{\sqrt{3}}{2}s
I can plug s into the height formula and the height formula into the area like this
A=\frac{1}{2}(\frac{10-x}{6})(\frac{\sqrt{3}}{2})(\frac{10-x}{3})...
Hello I have this word problem that I am having problems solving. Hopefully someone can help
Here is it.
A piece of wire 10m long is cut into two pieces. On piece, of length x, is bent into the shape of a square. The other is bent into the shape of a equilateral triangle.
