http://www.mapleprimes.com/questions/205162-How-To-Write-A-Recursive-Function-With?ref=Feed:MaplePrimes:Tagged With function
<p>Dear All,</p>
<p>I am new to maple and trying to write a recursive function with two input variables, but when i execute the statement it shows error "Error, (in B) too many levels of recursion"</p>
<p>Following is the set of instructions which i am trying to execute:</p>
<p><strong>if n=1 then </strong></p>
<p><strong>B(m,n):=omega(m); </strong></p>
<p><strong>else </strong></p>
<p><strong>B(m,n):=sum(omega(j)*B(m-j,n-1),j=1..m-1)</strong></p>
<p><strong>end if</strong></p>
<p><strong><br></strong>After execution, i try to access B(1,1) or B(2,1), the following error occurs</p>
<p><em><strong>B(1, 1);</strong></em><br><em><strong>Error, (in B) too many levels of recursion</strong></em></p>
<p><strong><br></strong>I'll be grateful, if someone can help me to fix this problem. </p><p>Dear All,</p>

http://www.mapleprimes.com/questions/205122-How-Do-I-Perform-Numerical-Integration?ref=Feed:MaplePrimes:Tagged With function
<p>I have an arrays of data. One for x values, and one for y values. How can I obtain a numerical integration of y for a range of x values?</p>
<p>I have tried defining a function of X using ArrayInterpolation(x,y,X) and then calling evalf(Int(f,xmin..xmax)) but that gives an error message. (I don't seem to be able to paste into this window) The error message says</p>
<p>"Error, invalid input: evalf expects its 2nd argument, n, to be of type posint, but received numeric."</p>
<p>I thought I was using a form of the equation right from the help system.</p>
<p>I also tried the 2D version of integration, but it returns the difference of my limits times my function name.</p>
<p>I aslo tried AdaptiveQuadrature, but I can't get that to work either.</p>

<p>I would like to get some sort of table (maybe also a plot) that shows me the effect on the function if I change a variable.</p>
<p>For example, I have f(x,y,z)=x+yz</p>
<p>Now I would like to get a list with the results for f if I run z from, say, -10 to +10.</p>
<p>Is it also possible to do this with all variables at the same time?</p><p>I would like to get some sort of table (maybe also a plot) that shows me the effect on the function if I change a variable.</p>

http://www.mapleprimes.com/questions/204717-How-To-Convert-Into-Elementary-Functions?ref=Feed:MaplePrimes:Tagged With function
<p>Maple is providing answers with the gamma function and LambertW function. I am not a math major. Although I did take advanced engineering mathematics in grad school, I am not familiar with transcendental functions. </p>
<p>I did look at some of the help. I tried to use the convert command to convert to elementary functions, however it did not help. I looked at the definition for the Gamma function, GAMMA(z), and the upper incomplete Gamma function, GAMMA(a,z) that uses the generalized hypergeometric function 1F1. Looking at the generalized hypergeometric function 1F1 defintion, hypergeom(n, d, z), it references the general pochhammer function, pochhammer(z, a), and product functions, product(f,k=m..n). This all seems way too complicated. </p>

<p>Update: Some more background on the problem is as follows. R is the expected reliability say 90%. MTBF is mean time between failures in hours. t is the time period of operation excluding allowable downtime. n is the allowed number of failures. I am looking to find the MTBF needed to achieve a certain required reliability, with the number of failures allowed, and the up-time operational period, being defined by the requirements as well.</p>
<p>To clarify the simplification does not necessarily have to be closed form, and an approximation would be acceptable. (in Excel I currently am using iteration over a number of rows, then using the Goal Seek tool to find the MTBF, however this is less than desirable to have to do everytime when looking at different trade studies) I am not that familiar with how to use assumptions in Maple, and do not know what would be the appropriate assumptions to make when simplifying.

<p>Hello, i got the following problem. I have a function, say u(h,e) whith multiple exponents <img class="math" src="http://www.mapleprimes.com/MapleImage.ashx?f=0f4aa9edb1a85e488dbcb5bb6a15490d.gif" alt="((u(h,e))^(1/a))^a">. As long as Maple does not know that u(h,e) is positiv it won't make the simplification and return u(h,e) as expected. From my view i have two possibilites to solve this problem:</p>
<p>1) Define u(h,e) to be positive. Sounds intuitive, but i didn't manage to find the right definition</p>
<p>2) Give maple the function e.g. u:=e+h^2 and simplify the epression in uneval quotes with assumption positive for e and h.</p>
<p>Whereas I have solution 2, the problem is that i would need excessive amounts of uneval quotes '' at the start of my worksheet, not to run out of them.</p>
<p> </p>
<p>I definitly need my epressions in unevaluated forms and would be happy to hear any ideas.</p>
