Why does my CAS say false?
Solving for some equations on TI-89 family, Voyage 200, or TI-Nspire Family CAS handheld (includes: TI-Nspire CAS with ClickPad or TouchPad and TI-Nspire CX CAS) will sometimes return an answer of “false.” This is caused by the equation having a non-real solution.
What is the difference between solve and NSolve?
They are Solve and NSolve. Solve is used to algebraically solve an equation or set of equations. In either case, NSolve can be used to find a numeric solution to an equation or set of equations.
What does Invalid implied multiply mean?
Invalid implied multiply. For example, x(x+1) is invalid; whereas, x*(x+1) is the correct syntax. This is to avoid confusion between implied multiplication and function calls.
Can Mathematica solve transcendental equations?
Mathematica 7 for the first time allows systematic treatment of transcendental equations, providing exact representations of roots in a symbolic form suitable for general manipulation, and yielding validated global numerical results to any degree of precision.
How do you delete variables on TI Nspire CX?
Variables can be deleted from within the Calculator application via the DelVar command (press [MENU]→Actions→Delete Variable). Keep in mind that you can delete a variable that’s contained only within the current problem.
Does implied multiplication take precedence?
In this more sophisticated convention, which is often used in algebra, implicit multiplication is given higher priority than explicit multiplication or explicit division, in which those operations are written explicitly with symbols like × * / or ÷.
How do you calculate transcendental equations?
Numerical methods for solving arbitrary equations are called root-finding algorithms. For a graphical solution, one method is to set each side of a single variable transcendental equation equal to a dependent variable and plot the two graphs, using their intersecting points to find solutions (see picture).
