Thank you for your suggestion. I've just tried it on my TI-83 Plus SE and it gave me..
[[1 0 0 3]
[0 1 0 -1]
[0 0 1 4]]
I know that is the correct answer, but the textbook requires me to show all the steps. The problem is I am stuck midway to obtaining the answer. (See the first post...
The full question is as follows:
Solve the following system by the Gauss-Jordan elimination method.
2x + 5Y - Z = -3
X - Y + 4Z = 20
3X + 2Y - Z = 3
Indicate the row operation used in each step.
So as long as I obtain an answer, it is still correct no matter the method I use? If this is the case then my textbook is really odd... it states that (1,1) has to be either +/- 1 and that multiplication changes can only occur in one row when adding.
Gauss-Jordan Elimination Method Help!
Hi, I'm having a problem solving the following using the Gauss-Jordan Elimination Method. I am wondering if someone can help me...
i.e.
[ [2 5 -1 -3]
[1 -1 4 20]
[3 2 -1 3]]
I've tried solving it by... R1<-->R2, R2+(-1)R1, R3+(-3)R1...
help please: sequence problem
how do you solve this question please help! thx!
A current population is 2 000 000 and it increases 7% annualy. However each year a certain number of people die (this amount is constant for every year). How many people die each year if the population is to...
The derivative of e is 0 since e by itself is a constant (just like pi).
The derivative of e^(1+x) is [e^(1+x)][1][dx].
The derivative of e^x is (e^x)(dx)
Hope that clarifies things up for you.
yes, but i sort of used pythagerus to solve them, not vectors...
A, B, C i can do fine... but D, E, F bit sketchy... :confused:
So any help would be appreciated... Thanks!
Please help with problems please! All questions need to be solved using vectors.
See enclosure for questions :biggrin:
Thank you!
