Question: GENERAL SOLUTION FOR= v''(t)+v'(t)+v=0,






y(x) = 1/12*x^4+1/6*x^3+1/2*x^2+_C1*x+_C2


you have to "tell" maple "y(x)" is the unknow function..

why double post?







.......and x<=fsolve(......

i clearly remember that i have replied to this post before

and just curious


"Table of integrals, series and products" of Gradshteyn and Ryzhik


where can i get this ? is there a free PDF copy ?






maple returns me with an answer of



however my tutorial sheet says it should be sqrt(Pi)


which is correct?



so for this question

i wrote down the wrong equation? wrong limits?

doing by hand the last step gives me




gives me POSITIVE value which is as expected


what's wrong with




i dont know if they are tasks for maple

but i think it's easier of you just do them without maple



Q4 and Q5   clearly you have to take the 1st and 2nd diravitive of the function

1, diff(cos((1+sinx)^0.5))

with respect to ?? 


2. plot(int(cos((1+sinx)^0.5))
this one it shown me that "Warning, unable to evaluate the function to numeric values in the region; see the plotting command's help page to ensure the calling sequence is correct"

again sinx  should be sin(x)  and you might want to specify the range x=a..b^0.5),x=0..5)


sinx  should be  sin(x)

not work


4. maximum(cos((1+sinx)^0.5),x=0..5)


sinx  should be  sin(x)

not work, it call error


sinx  should be  sin(x)

same with question 4

a := Generate(set(integer(range=1..999999999999), 1000000))):


it dose NOT display any results but the actual output is stored in "a" as you have defined it to be

i like the shape of the solutions!


is it a real model of something?

what's your problem with maple
