    Finding speed with basically just distance.

    Hi, I'm currently in the process of trying to learn how to use quadratics to find out speed/distance/time etc. My program that I'm taking is often very unclear and skims over topics regularly. The example I was given to learn the process was fairly straightforward and easy to learn, however the...

    Finding the equation of a surface of revolution

    Can someone verify if my solution to this problem is correct please? We are given a curve \left ( C \right ) : y=0, (x+3)^{2}+4z^{2}-15=0 and it is asked to find the equation of the surface that is produced if C rotates around the line \left ( l \right ) : y=0, x=-3 Solution: From a...

    Finding velocity

    A car starts at rest, moves forward 22 m in 8 seconds, then comes to rest again. What distance does the car cover in its first 4 seconds of motion? When graphed it creates a triangle, and of course d = vt, or the area of the triangle. I suppose the average velocity would be 2.75 m/s, but...

    Finding the angle and axis lengths of an ellipse

    Hi, I have an ellipse defined by \|\mathbf{A}^{-1}v\| = 1, where v is a vector in the ellipse and \mathbf A is a real, invertible 2-by-2 matrix. How can I find the lengths of the axis of the ellipse as well as the angle of the major axis? I need to know this because I want to plot the ellipse...

    Finding the Inverse of a Function

    Find the inverse of the function. Confirm algebraically by showing that f(g(x) = x and g(f(x) = x. Then confirm graphically. 7). f(x)= √2x+3 How do I set this problem up? And what are the step to solving it? I've looked through my book but I haven't seen any problem with the g, f, and x and...

    Newbie to Pre-Cal (w/ Finding Inverse of Function question)

    I'm a high school student enrolled in a Pre-Cal course. I'm not very skilled when it comes to math, I've maintained C's and B's in each Math class I've ever been in and I've had to re-take a few of them.. I want to change that and keep my grades high this year. (Happy) Thank you everyone for any...

    Finding a basis

    Hi, I need to find a basis for the following subspace: V={[ a b c d]: 2a-4b+c=0; a,b,c,d are all in R} a subset of R4 I understand the definition of basis which means that it has to span the vector space and it has to be linearly independent, but I am having difficulty applying this. Any help...

    Finding the bases for range and kernel

    Hi, I have the following problem: A linear transformation G: P2 ---> P2 defined by G(h(x))=2x h’’(x) + h’(x) I need to find bases for the kernel and range of T. I understand the definition of kernel means that we have to set it equal to zero and the coefficients must all equal zero, but there...

    Finding the tangent to a circle equation given the circle equation

    Hi guys, first time poster here! There' this equation I don't quite understand. I'm given the following question: The tangent line to the curve (x^2) (y^2) − (2x^2) + (y^2) = 0 at the point (1, 1) is=? Not quite sure how to deal with the circle arranged that way? I really need to understand...

    finding line integral

    for part b , the author sub x =t , i dont understand why he did so , can it be y = t or others? or , it must be x=t ? in the book , i was also told that i can use x = r costheta , and y = r sintheta for circular path ... I'm wondering can i use in this case ?

    finding surface area using projection of plane

    by using double integrals , find the surface area (x^2) +(y^2) +(z^2) =4 that lies between plane z =1 and xy -plane why the surface area is only the ring part where the limit is sqrt rt 3 to 2 , why not the whole thong , namely from 0 to 2 ? (refer to the projection region on xy-plane)
