calculate the rate when teta =10

Question

the electrical resistance R of a conductor at a temperature Ø Os  is given by R=Ro (1+alpha teta+beta tete square) where alpha ,beta and Ro are positive constants. obtain the rate at which the resistance varies with temporature. calculate the rate when teta =10

Answer 1

??????????????? "obtaen the rate at which" ???????????

????? yu wanna kalkulate sumthun ???????????

????????? "oos is given" ?????????? yu gave it awae ????????? iz zat good or bad????????

??????????? huz this "teta" character...thats a straenj name for a persun
