If you are taking calc2, then you must know what sine and cosine functions, etc. are. What I am calling trigonometry you may have been taught as "precalc"

well, we know that L{1} = 1/s and, we know from our handy table of transforms that L{t^n f(t)} = (-1)^n F(n)(s) so, L{t^2} = 2/s^3

you have a function: y=2/x volume = Integral pi*r^2 dx where r = y = 2/x pi*Int(4/x^2 dx) [1,oo] now take it from there. piece of cake.

Find the volumes of the solids generated by revovling the region in the first quadrant bounded by the curve x=4y-4y^3 and the y-axis about the given axes: a. the x-axis b. the line y=1 NO idea how to set it up!!! HElP!!

At what constant, continuous annual rate should you deposit money into an account if you want to have $1,000,000 in 25 years? The account earns 5% interest, compounded continuously. Round to the nearest dollar.

Let f(t) be a function defined for all values of t. The Laplace Transform of f(t) is defined by: F(s)= [∘,](e^-st(f(t))dt). If the improper integral exists, Find the Laplace Transform for F(t)=t^2.

Hint: use the disk method Find the intersection of x² and y=6, which is x=±sqrt(6). You may want to integrate with x=-sqrt(6) to +sqrt(6) πf(x)^2 dx [equiv. to πr²] where f(x)=x²-1 [i.e. from y=1 to y=x^2]

Let R denote the region in the plane consisting of all points (x,y) where x ≥ 1 and 0 ≤ y ≤ 2/x. Let S denote the solid formed by rotating R about the x-axis. Observe that S is an unbounded region; that is, it extends indefinitely in the direction of the ...

**calc2 - derivation**

dP/dt = r P dP/P = r dt ln P = r t e^ln P = e^(rt) + C P = C e^(rt) when t = 0, e^(rt) = 1 so C = value of P when t = 0 so P = Po e^(rt)

the function is x = 4y(1-y^2) so you know it crosses the y-axis at -1,0,1 So you're dealing with the bump in QI from y=0 to 1 To revolve that about the x-axis, I'd suggest shells, so v = integral[0,1] 2pi r*h dy where r = y, and h = x v = 2pi integral[0,1] y(4y-y^3) dy = 2pi ...
