The two trigonometric functions defined for all real numbers are the

The two trigonometric functions defined for all real numbers are the sine and cosine functions.

Trigonometry functions are functions used to represents the ratio of the sides of a right-angled triangle. The SOH CAH TOA theorem is used to solve for sides and angles of the right triangle.

Examples of trigonometric functions that we have include:

Out of the examples of the trigonometry functions listed, only sine and cosine are the two trigonometric functions defined for all real numbers since the domain of both functions exists for all real numbers except tangent and other trigonometric functions that are periodic functions.

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
