1. Equation Background
The equation that Karissa is attempting to solve is 2x^3 – 5x^2 + 3x – 1 = 0. This equation arises from a complex mathematical model that simulates the motion of a particle in a fluid. Solving this equation will allow Karissa to determine the trajectory and velocity of the particle under various conditions.
2. Karissa’s Approach
Karissa begins by analyzing the equation and identifying its key features. She notes that the equation is a cubic equation, meaning that it has three roots. She also observes that the coefficients of the equation are integers, which suggests that the roots may be rational.
Based on these observations, Karissa decides to use a combination of algebraic techniques and numerical methods to solve the equation. She starts by trying to factor the equation, but she is unable to find any rational factors.
3. Solution Process
Since Karissa is unable to factor the equation, she turns to numerical methods to find the roots. She uses the bisection method, which is a root-finding algorithm that repeatedly divides the interval containing the root in half until the desired accuracy is reached.
Karissa starts by choosing an interval that contains at least one root. She then evaluates the equation at the midpoint of the interval. If the equation is equal to zero at the midpoint, then the midpoint is a root. Otherwise, the midpoint divides the interval into two subintervals, one of which must contain a root.
Karissa continues to bisect the subintervals until the desired accuracy is reached. In this case, she stops when the interval is less than 0.001.
4. Obstacles and Challenges
Karissa encounters several obstacles and challenges while solving the equation. One challenge is that the bisection method can be slow to converge, especially for equations with multiple roots.
Another challenge is that the equation has complex roots. This means that the roots are not real numbers, but instead are complex numbers. Karissa is able to overcome this challenge by using a complex root-finding algorithm.
