What are Algebraic Equations?

An algebraic equation is always a balanced equation that includes variables, coefficients, and constants.

In the form:

P = 0

Where P is a polynomial.

For example, x + 8 = 0 is an algebraic equation, where x + 8 is a polynomial. Hence, it is also called a polynomial equation.

What is an Equation?

An equation is simply defined as mathematical statements that express the relationship between two values. Usually, the two values are equated by an equal sign in an equation.

### Monomial Equation

An equation which has only one variable term is called a Monomial equation. This is also called a linear equation. It can be expressed in the algebraic form of;

ax + b = 0

### Binomial Equations

An equation which has only two variable terms and is followed by one variable term is called a Binomial equation.

This is also in the form of the quadratic equation. It can be expressed in the algebraic form of;

a(x^2) + bx + c = 0

Trinomial Equations

An equation which has only three variable terms and is followed by two variable and one variable term is called a Trinomial equation.

This is also called a cubic equation. In other words, a polynomial equation which has a degree of three is called a cubic polynomial equation or trinomial polynomial equation.

Since the power of the variable is the maximum up to 3, therefore, we get three values for a variable, say x.

It is expressed as;

a(x^3) + b(x^2) + cx + d = 0

Trigonometric Equations

All the trigonometric equations are all considered as algebraic functions. For a trigonometry equation, the expression includes the trigonometric functions of a variable.

Trigonometric Equations: cos2x = 1+4sinx

Trigonometric Values For Standard Angles

Each of the trigonometric ratios can be evaluated at different angles.

Some standard angles are given in this table for each of the ratios. From these standard angles, we can extend the evaluation of trigonometric ratios for any angles.
