find the length of longest iron rod that can be placed in a room of 40m long, 36m broad and 22√2high

thank u

#3 Re: Exercises » scilab programmes » 2014-01-01 02:16:55

there are only 3 elements in above example

#4 Re: Exercises » scilab programmes » 2014-01-01 02:11:08

for above vector to get 1st element A(1,1)

yes...

#6 Re: Exercises » scilab programmes » 2014-01-01 02:01:26

in scilab array set values in vector form for ex. A=[1 2 3]

#7 Re: Exercises » scilab programmes » 2014-01-01 01:46:46

zeroing the array element means

scilab program to obtain non fibonacci series

thank you:)

#10 Re: Exercises » scilab programmes » 2014-01-01 01:10:46

question is
scilab program to find the root of eqn f(x,a)=a*cos(x)-x*e^(-a*x) for different values of a∈[1,10]

#11 Re: Exercises » scilab programmes » 2014-01-01 01:04:11

i dont know.
in question it is not clear that a is continous or not

#12 Re: Exercises » scilab programmes » 2013-12-31 22:18:47

i dnt knw hw to insert the condition that a∈[1,10] in newton raphson method

#13 Re: Exercises » scilab programmes » 2013-12-31 20:09:36

non fibonacci sequence is 4,6,7,9.10,11,12,14,15,16,17,18,19,20,...

ok....

i need scilab progam for
1. to obtain fibonacci series
2.to obtain non fibonacci series
3. to find the root of the equation f(x,a)=a*cos(x)-x*e(-a*x) for different values of a∈[1,10]
it is imporant for my exams

The spiral has the property that the angle φ between the tangent and radial line at the point (r, \theta) is constant. This property can be expressed in differential geometric terms as

arc cos[(r(θ), r'(θ)/||r(θ)||*||r'(θ)]=arctan(1/b)=⏀

#17 Re: Help Me ! » logarithmic spiral » 2013-09-22 04:07:06

is there any particular formula?
without using any formula how to find θ
as radius varies  θ also varies right?

in polar coordinates, the logarithmic spiral is given by r=ae^(bθ)
how find θ and how to draw logarithmic spiral

thank you

thank you
which is that journal devoted to fibonacci sequence

#21 Re: Introductions » Hi :) » 2013-09-19 05:11:29

this is similar to fibonacci spirals

#22 Re: Introductions » Hi :) » 2013-09-19 05:03:35

okay.
then what are logarithmic spirals
