2.  The equation with one variable. At P(atm) equals 0.5 atm, What is T ? ? ?

3. 1. Bisection method 2. Secant method 3. Newton’s method (Newton-Raphson)

11.  Newton’s method is more effective than any other method just depend on the number of iteration.  Before figuring out the answer, both bisection and secant method need two numerals, one is bigger and one is smaller than the answer. That means you should know an approximate value when using bisection and secant method. So, If you have no idea about the answer then selecting Newton’s method is suitable choice.
