Let f(t)=( (cos t)^3, (sin t)^3 ) Let S = {f(t) | t E R} Draw a sketch of S. ========================== Now I know that S is x^(2/3) + y(2/3) = 1 What is the fastest way to draw a really rough sketch of this? (bascially I need the shape) I am very lost in situations like this. I was never...

three small, negatively charged spheres are located at the vertices of an equilateral triangle.The magnitudes of the charges are equal. Sketch the electical field in the region around this charge distribution, including the space inside the triangle. ok..so all i know is that density of field...

I am pulling my cousin who has a mass of 10kg, geets all bundled up and sits in the sled, which has a mass of 15kg. He yells ready,set,go and I start to pull him across the snow. I am pulling the sled at an angle of 50degrees with respect to the horizontal. Assume that the coefficient of static...

so, for the very specific cases of linear systems i can identify what shape it will be after determining the eigenvalues, but i really do not know how to go about sketching the phase planes. can someone give me a method?

Homework Statement Roughly sketch e^x + x - 2 to show that it has only one root. This is given before we learn derivatives and the curve sketching algorithm, but after we have gone through limits and asymptotes. The Attempt at a Solution Well, the graph of e^x - 2,is easy enough, a...

Hey everybody, I hope that you can help me with this question: The current through a 3 µF capacitor is shown in the figur: http://peecee.dk/?id=70914 At t=0, the voltage is v(0)=10. Sketch the voltage, power, and stored energy to scale versus time. - I will start to find the voltage...

silly question. didnt know where it was meant to go so i just put it here as safest option:) suppose a curve C is defined by, r(t) = (sint, cost) with 0 \leq t \leq 2\pi if a sketch of C was required then would you simply just draw the graphs for sint and cost?

Homework Statement Sketch on the same axis the graphs of y = |x| and y = 2 - x^2. For which values f x is the inequality |x| < 2 - x^2 Homework Equations The Attempt at a Solution I don't really understand what it is asking me to do, I've sketched the two curves, y = |x| 45...

sketch the graph of a function that has no local minimum at 2 and is differentiable at 2 this is confusing, how come this is an upside down parabola, it makes sense, but how do i know what kind of graph to draw

Circuit ...LOSt :confused: Homework Statement A sandard cell or 1080V gives a balance length of 512 mm on a potentiometer. If the p.d across a standard 10.0 (ohm) resistor in a circuir gives a balance length of 784 mm, calculate the current in the circuit with the 10.0 (ohm) resistor. Draw...

could you give me the method of sketching the graph of a step function here is an example: N(t)=25(2||t+2/2||-t) thanks a lot for your help

I'm going to sketch the graph of the eq. 4x^2 + 9y^2 = 144 This is an ellipse with its center at the origo and major semiaxis 6 and minor semiaxis 4. But how do I find the foci?

hey guys, having trouble with this one: y=x + 4/(x-1) i have found 1st and 2nd derivatives. Minimum turing point at (1/2, 15/4) and there are no points of inflexion. there is an asympote at x=1...right. This line is more than just that though isn't it? how can u tell that you got...

Wow, I totally forgot how to do these. I have a graph of a line, but it does not say the function. I have to sketch the antiderivative. Does anyone have any links or advice to start me out. TIA

Hello, I'm trying to experiment with eliptic curves a little, but I have a problem with graphing elliptic curves. For example, neither mathematica nor geometry sketchpad graph negative values of curves. Is there anyway to force mathematica or geo sketchpad to plot also negative values of x? F...

a) sketch the graph of the function f(x)=square root X b) on the same set of axes, graph y=f^-1(x), y=-f^-1(-x) so I did a chart, but i don't know if its right...I don't think its right :confused: f(x)=squareroot x X Y 0 0 1 1 4 2 9 3 y=f^-1(x) X Y 0 0 1 -1...

"By sketching appropriate graphs (one of them a straight line) show that the function f(x) = 2sin(x) - 3x + 2 has only one real root." this one confuses me from the word go. how can you sketch a straight line of that function when it has sin as part of it?

Here is the problem I'm having some trouble with. The answer is fairly simple, it is the power of the e function. (the parabola x = y^2 + 1) I'm not sure how to get that, i could use some hints/help, thanks!

For a particle of mass m moving in a potential V(r) = -b/r^2 where the constant b>0 obtain the equation r = r(\phi} of the trajectory for the particular states of motion with total energy E = 0 and angular momenta such that \frac{L^2}{2m} < b SKetch the trajectory and discuss the motion for...

Hi guys, I know this is a dumb question, but I have to ask. We are supposed to sketch the curve of y=x/(x-1)^2 using the guidelines for curve sketching such as domain, intervals of increase/decrease, concavity...ect. For the most part on this question I think I have done this all right, it...

How can i sketch the equipotential lines for an isolated negatively charged particule?

Hey guys, just needed help with two questions, any help would be appreciated 1. a radar antenna on a ship tha tis 4km from a straight shoreline revolves at 32 rev/min. How fast is the radar beam moving along the shore line when the beam makes an angle of 30° with the shore? Give an exact...

Hi all forum guys! Many days ago I am looking for a simple pancake motor to build in home. I need a diagram or a description of the armature, magnets , coils, and i can't get a article appeared in Popular Mechanics about it...? If some knows about this. Please let me know it. Thanks Mr. Ju...

Sketch the region enclosed by x+y^2=12 and x+y=0. Decide whether to integrate with respect to x or y. Then find the area of the region. first thing i did was solve for x for each equation then set them to each other and got: 12-y^2=-y y^2-y-12=0 found the points of intersection of y...

Got me some energy e-states Psi(x,t) = blah blah.. I am asked to normalize, blh blah blah.. got that. Then I'm asked to sketch mod(Psi1).. what the heck is mod? I know what mod is in regards to number theory, but obviously this is a different term. Can't find it for the life of me on any sites...

can anyone teach me how to use a different coordinate system to sketch the graph of (x-2y)=sin(pi(x+y)). i have totally no idea

A particle moves on a circular orbit in a central force field. The origin of the force lies on the circle. Find the polar equation of the orbit. I am confused as to how to set up this question.
