    Linear Algebra - Change of Basis

    I know that q3a is just the standard matrix. I am used to solving q3b by using the equation in part (d). but q3b is asking to solve by a method similar to the method in q2 like the example i have written. the thing is I am not used to solving it using matrices i know how to solve polynomials and...

    Linear Algebra - Change of Basis

    I don't know how to imply it. working with matrices confuses me :S

    Linear Algebra - Change of Basis

    an example of what i mean is : I can do an example like 2c: T(1) = 1 + 0 = 1 = 1/2(1+t) + 1/2(1- t) + 0(t^2) = (1/2 1/2 0) T(t) = t + 1 = 1(1+t) 0(1-t) + 0(t^2) = (1 0 0 ) T(2) = t^2 + 2t = 1(1+t) + (-1)(1-t) + 1(t^2) = (1 -1 1) so [T](B-->C) is equal to the matrix : [1/2 1 1] [1/2 0 -1]...

    Linear Algebra - Change of Basis

    Hi please i need help in number 3 of the tutorial questions. It is not an assignment its just a tutorial (read title in the image). I am currently studying for my final and i need help in (3b). the only way I am thinking of solving this questions is to use the equation given in part (d). But...

    Can RFID Sensors Revolutionize Total Knee Replacement Surgery?

    Ive done the requirements document and the design document and now i have the final project report. This was given to us at the beginning of the semester: RFP Australia maintains one of the world’s most reliable databanks on joint replacements, so much so that the US FDA relies on...

    Can RFID Sensors Revolutionize Total Knee Replacement Surgery?

    I know it doesn't make such sense i wanted to talk about a simple cobalt chromium design with a microcontroller that fits in the tibial part something like this ( http://www.gizmag.com/go/6435/ ) but my group members wanted something new and different. Answering you quesntions: 1. 1...

    Can RFID Sensors Revolutionize Total Knee Replacement Surgery?

    Hi I am asked to make 40 page report about a new total knee replacement with wireless technology as a final assignment. This is what i thought of: The total knee replacement will have 5 sensors on each part of the knee upper part and lower part(femoral and tibial) each of the 5 will be...

    Linear Transformations, Linear Algebra Question

    but how do i get [T]B' ,B ? like [T(v1)]B' ,B I know how to do it with polynomials but I have no idea with matrices.

    Linear Transformations, Linear Algebra Question

    Hi can anyone give me some hints with this question thanks A = \begin{pmatrix} 3 & -2 &1 & 0 \\ 1 & 6 & 2 & 1 \\ -3 & 0 & 7 & 1 \end{pmatrix} be a matrix for T:ℝ4→ℝ3 relative to the basis B = {v1, v2, v3, v4} and B'= {w1, w2, w3} v1 = \begin{pmatrix} 0 \\ 1 \\ 1 \\ 1 \end{pmatrix} v2 =...
