Can Computers Solve Transcendental Equations?

In summary, transcendental equations are those that cannot be described solely by elementary operations such as addition, subtraction, multiplication, division, and nth root. They are different from algebraic equations, which can be solved using these operations. While computers can approximate solutions to transcendental equations, they cannot provide exact solutions as they require symbolic manipulations that computers are not capable of.

Hi
I wanted to find out what transcendental equations actually are. Can the computer solve such equations?
Thanks,
Sunayana.

Elementary Operations :
+,-,*,/,nthroot()

If any equation can be described by these operations alone, then such an equation is called algebraic equation. If not, they are called transcendental equations.

Can computers solve such equations?
Approximate solutions ofcourse, exact solutions ofcourse not!

I think you're under a slight misapprehension: computers can't (even) solve (algebraic) equations generally, if you mean outputting a number in a recognizable form that is a/the precise answer. There are almost no equations algebraic or transcendental that have solutions that can be output as a finite binary expansion which is all a computer deals with (possibly up to base change). I am ignoring the few symbolic manipulations that can be done.i'd like to add that algebraic things involve finitely many of those operations, so that

2=1+x+x^2/2! + x^3/3!+...

is not algebraic (its exact solution is of course x=log(2)...

Related to Can Computers Solve Transcendental Equations?

1. What are transcendental equations?

Transcendental equations are mathematical equations that involve transcendental functions, such as trigonometric, logarithmic, or exponential functions. These functions cannot be expressed as a finite combination of algebraic operations, making the equations more complex to solve.

2. How are transcendental equations different from algebraic equations?

Algebraic equations involve only algebraic operations, such as addition, subtraction, multiplication, and division, and the variables are raised to integer powers. On the other hand, transcendental equations involve transcendental functions and the variables can be raised to any real power.

3. What are some examples of transcendental equations?

Some examples of transcendental equations are sin(x) = 2x, e^x + 3x = 10, and log(x) + 2x = 5. These equations involve transcendental functions, making them more difficult to solve compared to algebraic equations.

4. How do you solve transcendental equations?

Transcendental equations can be solved using various methods, such as graphical methods, numerical methods, and analytical methods. Graphical methods involve plotting the equations on a graph and finding the intersection points. Numerical methods involve using algorithms to estimate the solutions. Analytical methods involve using algebraic manipulations to isolate the variable and solve for it.

5. What are some applications of transcendental equations in science?

Transcendental equations have many applications in science, particularly in physics and engineering. They are used to model physical phenomena, such as wave propagation, heat transfer, and fluid flow. They also play a crucial role in solving differential equations, which are commonly used to model natural phenomena.
