How do we determine the curve (the equation) for this? ???

[marcelino]

paano ko madedetermine yung in between values?  ...for instance 54%RH?

i believe this is interpolation pero anong klaseng interpolation?

limot na ako ng math ko ah!

[akhen]

Aw.. nakalimutan ko na din to... After kc ng board exam nagsystem restore ako ng utak ko e. hehe

hahaha... sayang din nun! heheheh

hirap talga pag di mo naman ginagamit, nakakalimutan.

ang alam ko kasi, interpolation to. limot lang ako kung anong type of interpolation. di dito applicable yung linear interpolation.
kanina pa ako actually hanap ng hanap sa internet, pero parang walang direction kasi di ko naman talga alam ang hinahanap ko!
hehehe

[marcelino]

got it...

anyway share ko na din para kung sakaling may mangailangan din.

f(x) = (5000*(x-30)*(x-40)*(x-50)*(x-60)*(x-70)*(x-80)*(x-90))/((20-30)*(20-40)*(20-50)*(20-60)*(20-70)*(20-80)*(20-90))+(1300*(x-20)*(x-40)*(x-50)*(x-60)*(x-70)*(x-80)*(x-90))/((30-20)*(30-40)*(30-50)*(30-60)*(30-70)*(30-80)*(30-90))+(310*(x-20)*(x-30)*(x-50)*(x-60)*(x-70)*(x-80)*(x-90))/((40-20)*(40-30)*(40-50)*(40-60)*(40-70)*(40-80)*(40-90))+(87*(x-20)*(x-30)*(x-40)*(x-60)*(x-70)*(x-80)*(x-90))/((50-20)*(50-30)*(50-40)*(50-60)*(50-70)*(50-80)*(50-90))+(31*(x-20)*(x-30)*(x-40)*(x-50)*(x-70)*(x-80)*(x-90))/((60-20)*(60-30)*(60-40)*(60-50)*(60-70)*(60-80)*(60-90))+(13*(x-20)*(x-30)*(x-40)*(x-50)*(x-60)*(x-80)*(x-90))/((70-20)*(70-30)*(70-40)*(70-50)*(70-60)*(70-80)*(70-90))+(5.7*(x-20)*(x-30)*(x-40)*(x-50)*(x-60)*(x-70)*(x-90))/((80-20)*(80-30)*(80-40)*(80-50)*(80-60)*(80-70)*(80-90))+(2.7*(x-20)*(x-30)*(x-40)*(x-50)*(x-60)*(x-70)*(x-80))/((90-20)*(90-30)*(90-40)*(90-50)*(90-60)*(90-70)*(90-80))   

change the 'x', and get what you want!
that is the solution!!! hehehe

its called Lagrangian interpolation

[rdpzycho]

haba ah. hehehe. minsan kapag ganyan, linear ko na lang doon sa pagitan. hehehe.

[marcelino]

hehehehe... nakakatamad icompress... pero kinokompress ko kasi kailangan idocument! heheh
sinulat ko muna sa notepad, tapos paste sa python. with given 'x'. patay sila!

linear din sana... kaso magkalayo masyado... normally nasa 40 -80 %RH sa Pinas, pero tignan mo sa table yung mga pagitan...

ff(x)=(5000*(x-30)*(x-40)*(x-50)*(x-60)*(x-70)*(x-80)*(x-90))/((20-30)*(20-40)*(20-50)*(20-60)*(20-70)*(20-80)*(20-90))
   +(1300*(x-20)*(x-40)*(x-50)*(x-60)*(x-70)*(x-80)*(x-90))/((30-20)*(30-40)*(30-50)*(30-60)*(30-70)*(30-80)*(30-90))
   +(310*(x-20)*(x-30)*(x-50)*(x-60)*(x-70)*(x-80)*(x-90))/((40-20)*(40-30)*(40-50)*(40-60)*(40-70)*(40-80)*(40-90))
   +(87*(x-20)*(x-30)*(x-40)*(x-60)*(x-70)*(x-80)*(x-90))/((50-20)*(50-30)*(50-40)*(50-60)*(50-70)*(50-80)*(50-90))
   +(31*(x-20)*(x-30)*(x-40)*(x-50)*(x-70)*(x-80)*(x-90))/((60-20)*(60-30)*(60-40)*(60-50)*(60-70)*(60-80)*(60-90))
   +(13*(x-20)*(x-30)*(x-40)*(x-50)*(x-60)*(x-80)*(x-90))/((70-20)*(70-30)*(70-40)*(70-50)*(70-60)*(70-80)*(70-90))
   +(5.7*(x-20)*(x-30)*(x-40)*(x-50)*(x-60)*(x-70)*(x-90))/((80-20)*(80-30)*(80-40)*(80-50)*(80-60)*(80-70)*(80-90))
   +(2.7*(x-20)*(x-30)*(x-40)*(x-50)*(x-60)*(x-70)*(x-80))/((90-20)*(90-30)*(90-40)*(90-50)*(90-60)*(90-70)*(90-80))

mas malinaw sa mata!

[rdpzycho]

hehehe. mas madalai i-align 'yan kung courier ang font.

[marcelino]

ayos ah... di ko yan alam. kahit pala sa threads, applicable yan. heheh

another learning tonight.
