how do i solve this? with matrix?
you have 4 unknown variables and 4 equasions.
i need to know values of a,b,c,d.
#e is 2.71 or something like that.
^ means power (3^2=3D9)
135=3Da*1000^b*#e^(c*(0.2))*(0.1)^d
360=3Da*950^b*#e^(c*(0.4))*1^d
765=3Da*900^b*#e^(c*(0.6))*5^d
130=3Da*850^b*#e^(c*(0.2))*(0.1)^d
i tried it with Derive but it solves a shit
is there any other program i can get that will solve it for me?
here is verions of four equasions in C:
135=3Da*pow(1000,b)*exp(c*(0.2))*pow(0.1,d)
360=3Da*pow(950,b)*exp(c*(0.4))*pow(1,d)
765=3Da*pow(900,b)*exp(c*(0.6))*pow(5,d)
130=3Da*pow(850,b)*exp(c*(0.2))*pow(0.1,d)
and in BASIC:
135=3Da*1000^b*EXP(c*(0.2))*(0.1)^d
360=3Da*950^b*EXP(c*(0.4))*1^d
765=3Da*900^b*EXP(c*(0.6))*5^d
130=3Da*850^b*EXP(c*(0.2))*(0.1)^d
and in FORTRAN:
135=3Da*1000**b*EXP(c*(0.2))*(0.1)**d
360=3Da*950**b*EXP(c*(0.4))*1**d
765=3Da*900**b*EXP(c*(0.6))*5**d
130=3Da*850**b*EXP(c*(0.2))*(0.1)**d
and in PASCAL:
135=3Da*POW(1000,b)*EXP(c*(0.2))*POW(0.1,d)
360=3Da*POW(950,b)*EXP(c*(0.4))*POW(1,d)
765=3Da*POW(900,b)*EXP(c*(0.6))*POW(5,d)
130=3Da*POW(850,b)*EXP(c*(0.2))*POW(0.1,d)
ok, enough.
