i have used polyfit function to do so and i have got that plot the red one is the polyfit function , the blue is the one i have it data , as you see they are close to each other but
P(t)= =2.995134969444502*(10^3)*(t^10)+(2.454194242827056*(10^3))*(t^9)-(3.074449680687996*(10^4))*(t^8)-(1.831814183200164*(10^4))*(t^7)+(1.225116448716314*(10^5))*(t^6)+(1.225116448716314*(10^5))*(t^5)-(2.265044070414277*(10^5))*(t^4)+(6.259310423328208*(10^2))*(t^3)+(1.720638633336634*(10^5))*(t^2)+(8.587517861009773*(10^4))*t+(2.102731998692876*(10^5));
so P(t=0)= (2.102731998692876*(10^5)) different from zero
what should i do to make it close ?
