For each variable in the expression, give it a value.Enter the expression defining the function.It is possible to evaluate an arbitrary function (of one or more variables) at different arguments without re-entering the function’s definition every single time. The solution: Solve the equation B÷2+B+3B=180. Here’s an example problem: The 3 angles in a triangle are A, B, and C. The algorithm can easily hang, fail, or give a wrong answer, so beware – it is not the solution to all your problems.Īlthough linear equations are simple to solve in theory, letting the calculator solve it for you can still save some algebraic manipulation. However, this step is generally not necessary for linear equations due to the nature of Newton’s method.Īs mentioned in the manual, the calculator internally uses Newton’s method (but with numerical differentiation) to solve equations. Try to give a value near a solution, or else solving will be slow or will fail. Give an initial guess for the variable and press the equals button.Enter the equation on the formula line.To solve an arbitrary equations of one variable: Polynomials equations and linear systems come up quite often on tests and contests in mathematics, physics, and chemistry, which makes this feature quite useful. Enter the number of variables, which is also the number of equations ( 2 or 3).Go to EQN mode and stay at the Unknowns? section ( MODE MODE MODE 1).

To solve a system of linear equations of 2 or 3 variables: Scroll through the solution set (which may have complex values).Enter the 3 or 4 (real) polynomial coefficients, from highest degree downward.Go to EQN mode and scroll over to the Degree? section ( MODE MODE MODE 1 ?).To solve a quadratic or cubic polynomial equation: Standard tricks Solving polynomials and linear systems
