Maple help! (1 Viewer)

Could somebody show me how to do this question?

 

[McLake]

Have you learnt to write recursive functions yet?

If so, write a recursive function. Something like this (note this is NOT maple code, just a gist of what teh code would be):

findXfunction :: (x : integer)

if x = 0
return 1.00
else if x = 1
return 2.50
else
return log(findXfunction(x - 1) + 7) / (6*(findXfunction(x-2)))

end function.

The alternative is to write a loop ...

*really isnt looking forward to that maple exam*

I haven't even booked my maple exam...and I'm scared because I don't know how to use Maple except for the easy things like in the assignment...

Neither, that's why I booked mine for Thursday Week 12...more preparation time.

GO MATH 1031!!!

The practice test is now available. Follow the link below. You must score at least 3/10 in a practice test before the end of week 10.

Once you have scored 3/10 in the practice test, a link to the final test will appear. You are allowed 5 attempts at the final test and your best score will count 5% towards your final MATH1031 mark.

You can have unlimited attempts at the practice test and they do not count towards your final mark, so try as many as you like.

A good strategy might be to work through a couple of the worksheets above, and then have a go at a practice test, and only attempt the relevant questions. Then go back and try another of the worksheets above.

In case you don't get whats going on, we can do the tests at home, uni, whatever! WITH GUIDANCE! w00T!

OMG!

That's so lucky!

Our is a test in the lab computers or something...can't cheat >.<

The maple test shouldnt be too hard since they are giving us the manual while we are doing it, so we just look up the functions we need in the test.

Hint: Look up the rsolve function in your computing notes.

Alternatively you can create an algorithm to do it. Here's a simple maple algorithm which simply computes the sum of squares up to a number for example:

sumsq := proc(n)
sumsq(0) := 0;
sumsq(n) := sumsq(n-1) + n^2;
end proc;

Might as well ask another Maple question... my problem is i can't express the definte integral like the anwser (which is only 'x') .. pls see attachment.

The above line is the question itself... the bottom 'colour' line is my 'wrong' attempt to solve that problem...

Thank you

i dont know any of this!

i think it has something to do with difference equations although im not sure

 

[truly-in-bliss]

its cool how u guys can do it at home ...

can u take your time with it or is there like a set time ur meant to finish the test in?

 

[babydoll_]

nope as long as we do the final one by wk 11 i think

 

[t-i-m-m-y]

in MATLAB that would be really easy. similar syntax

babydoll_: define the function x(n). then evaluate x(n) at n=752 voila!

EDIT: need to use looping syntax to do it

don't even think about cheating dude.

btw we've had ours. do the practice test. it exactly the same. just diff numbers. i'm assuming similar style for 1131/1141

 

[Dash]

I have a quesion...
How do we input the inverse of tan(x) in maple?

 

[enak]

Dash:
arctan(x)


Btw, i have a question, how do we input something like, we get 3 equations
sinpi(x) if x<0
x^2 is 0<=x<=1
exp(1-x) if x>1

then plot the graph of g over the interval [-1,2]
evaluate (exactly) the integral of g over the interval [-1,2]

 

[enak]

oooh, dont worry, i skipped the plotting piecewise-defined functions part in the notes

 

[enak]

Hmm, one question
How do u do operations on matrices?
Like form the augmented matrix for the system Ax = b and use maples row operation commands to reduce this augmented matrix to row echelon form?

 

[t-i-m-m-y]

its easy in MATLAB, as matlab treats everything as a matrix and such. maple is more symbolic, and i dont have a clue to be honest
