I'm writing a poem and came across these two lines.

Grey skies pouring rain

Leaves' tears float about

Does it make sense to say the "tears", symbolized by the rain, are "floating" on the leaf?

Basically I'm trying to create an image of a rainy day in fall where the picture is temporarily zoomed in onto the water droplets on the leaves.

Thanks

As humans get more knowledgable, there will be more stuff for students to learn.

So for example, will all students eventually learn Calculus in high school as a new standard?

How do we do this without using a graphing calculator? We are only allowed simple scientific calculators on midterms.

The answer should be in degrees. I think it's around 42.

Thanks

How will a nation's gov't know a citizen didn't pay income tax? What if the income is from foreign stock trading?

I'm an intermediate skier and I plan to ski this winter after having a one season break. Since I'm lazy, I don't usually exercise and do not drink milk either. Any tips on preparing myself for the season? I'm a caual skier so I'm out there to have fun but best if I can do some preparation but I'm clueless in this aspect so I need your tips!

Thanks =)

y'' + 6y = f(t)

y(0) = 0

y'(0) = -2

where,

f(t) = t, 0 =< t <1

f(t) = 0, t>=1

Thanks!

Find the mass and centroid of the curve with parameterization x = t -sint, y = 1 - cost, where 0 =< t =< 2pi and the constant density p=1.

Thanks

Find the surface area of the part of the sphere x^2 + y^2 + z^2 = 1 that lies between the planes z = a and z = b, where 0 < a < b < 1.

Thanks in advance =)

Let T be the solid region in space bounded by the surface with equation p = 2 cos(phi) in spherical coordinates. Find the average distance of the point of T from the origin.

Thanks in advance! =)

Consider the first octant cube with edge lengths 1 ( and corner at the origin ). Suppose it has density function f ( x, y, z) = x^2 + y^2 + z^2. Fine the coordinates of the centroid of this cube.

Thanks in advance! =)

Fine the volume of the solid region bounded by the

sphere: x^2 + y^2 + z^2 = 4

and

paraboloid: z = x^2 + y^2

y'' + y^2 = 1

y(0) = 1

y'(0) = -2

Thanks in advance!

Is it to store and retrieve data in an efficient manner? Elaborate please thanks =)

The lifespans of light-emitting diodes are known to be exponentially distributed, with a mean

lifespan of 12 years.

Suppose that 45 diodes are selected at random. What is the probability that the average

lifespan for this sample is between 11:5 and 12:3 years?

Answer: 0.1778

Thanks in advance. =)

The period of T of a simple pendulum is given by T = 2pi sqrt(l/g).

Using differentials, find the error made in computing T by using l = 2m and g = 9 m/s^2 if the true values are l = 1.95m and g = 9.81 m/s^2.

Thanks in advance. =)

If W = z.sin(y/x), where:

x = 3r^2 + 2s

y = 4r - 2s^3

z = 2r^2 -3s^2

Find:

a) dw/dr

b) dw/ds

Thanks in advance. =)

Find the volume of the region common to the intersecting cylinders:

x^2 + y^2 = a^2

x^2 + z^2 = a^2

Thanks in advance! =)

Find the local maxima and minima of:

f(x,y) = x^3 + y^3 - 3x - 12y + 20

How would you do it? Would you use Lagrange multipliers?

Thanks in advance. =)

Use Lagrange multipliers to find the shortest distance from the origin to the hyperbola

x^2 + 8xy + 7y^2 = 225, z = 0.

Thanks in advance! =)

We were given the following code from the last assignment to use for singly linked list, but we're supposed to add in a getPrevious() and setPrevious() method. The following code works for the singly linked list as I completed the assignment and got 100%.

I searched online and read my book but couldn't find a solution.

For a singly linked list I would start from the head and iterate until the *getNext() == current* or something of the like. Obviously that beats the purpose of a doubly linked list, so any ideas?

Thanks in advance! =)
