can u pls solve this? i tried all what i know.

the elationship between the resistance R of the thermistor and the temperature is given by

(1/T)-1.129241*10^(-3)=2.341077*10^(-4)*log(R)+8.775468*10^(-8)*(log(R))^(3)

where T is in Kelvin and R is in ohms.

A thermistor error of no more than 0.01C is acceptable. To find the range of the

resistance that is within this acceptable limit at 19C , we need to solve

1/19.01+ 273.15=1.129241×10^(-3) + 2.341077×10^(−4)*ln(R) + 8.775468 × 10^(−8)* {ln(R)}^(3)

and

1/18.99 + 273.15= 1.129241× 10^(−3) + 2.341077 × 10^(−4) ln(R) + 8.775468 × 10^(−8) {ln(R)}^3

Use Newton’s method to find the resistance at 18.99C. Find the absolute relative

approximate error at the end of each iteration, and plot relative approximate error versus

iteration number.

i wrote program this but i cant take the plot of all iteration what do u sugges??
