What are the uses of trigonometry in various fields?
Scientific fields that make use of trigonometry include: acoustics, architecture, astronomy , cartography, civil engineering, geophysics, crystallography, electrical engineering, electronics, land surveying and geodesy, many physical sciences, mechanical engineering, machining, medical imaging , number theory, oceanography, optics, pharmacology, probability theory, seismology, statistics, and visual perception. Various types of equations can be solved using trigonometry. For example, a linear difference equation or differential equation with constant coefficients has solutions expressed in terms of the eigenvalues of its characteristic equation; if some of the eigenvalues are complex, the complex terms can be replaced by trigonometric functions of real terms, showing that the dynamic variable exhibits oscillations. Similarly, cubic equations with three real solutions have an algebraic solution that is unhelpful in that it contains cube roots of complex numbers; again an alternative solution exists in terms of trigonometric functions of real terms.
How does Trigonometry relate to math?
It is a branch of maths. The word 'trigonometry' means, 'measuring triangles'. Trigon (polygon) = triangle metry = to measure. Both parts of the roots are from Classical Greece.
What is the value of x in ax2 bx c0?
ax2 + bx + c = 0 , find the value of x . b2-4ac>o x is real (2 different values will solve) b2-4ac=o -> a double root (a single real number will solve it) x=real numbers. b2-4ac<0 x= two complex number roots (either pure imaginary or a complex number with real and imaginary components)
What is one-to-many relation in mathematics?
It is a relationship where one input results in many outputs. A common example is square roots.the square root of 4 is -2 as well as +2. In fact, all positive numbers have two square roots: one negative and one positive. So that is an example of a one-to-many relation.Mathematically, such a relation is not a function. However, by restricting the codomain (range) to only non-negative (or only non-positive) values the relation can be made into a function.Similarly, the inverse functions for all six trigonometric ratios must have restricted codomains. Otherwise, because of their periodicity, each input has infinitely many outputs.For example, arctan[sqrt(3)] = pi/3 + k*pi = pi*(1/3+k) radians, where k is any integer.
Can the answer to a quadratic equation be a decimal?
Yes. You can calculate the two roots of a quadratic equation by using the quadratic formula, and because there are square roots on the quadratic formula, and if the radicand is not a perfect square, so the answer to that equation has decimal.
Formula of quadratic equation if roots are given?
A quadratic equation has the form: x^2 - (sum of the roots)x + product of the roots = 0 or, x^2 - (r1 + r2)x + (r1)(r2) = 0
Why do you use square roots to solve quadratic equations?
Because it's part of the quadratic equation formula in finding the roots of a quadratic equation.
How do you formulate quadratic equation that can be solve by extracting square roots?
By using the quadratic equation formula
Why do mathmaticians use the quadratic formula?
To find the roots (solutions) of a quadratic equation.
What is the sum and product of roots of a quadratic equation?
the sum is -b/a and the product is c/a
What form is the solving for the roots of quadratic equations?
Using the quadratic equation formula or completing the square
What happens in the quadratic formula that yields no real solutions?
If the discriminant of b2-4ac in the quadratic equation formula is less than zero then the equation will have no real roots.
What is Factor-Factorproduct relationship?
The Factor-Factor Product Relationship is a concept in algebra that relates the factors of a quadratic equation to the roots or solutions of the equation. It states that if a quadratic equation can be factored into the form (x - a)(x - b), then the roots of the equation are the values of 'a' and 'b'. This relationship is crucial in solving quadratic equations and understanding the behavior of their roots.
What are the roots of the quadratic equation below?
That depends on the equation.
When do you use the quadratic formula?
When you need to find the roots of a quadratic equation and factorisation does not work (or you cannot find the factors). The quadratic equation ALWAYS works. And when appropriate, it will give the imaginary roots which, judging by this question, you may not yet be ready for.
Why cant the zero product property be used to solve every quadratic equation?
If the discriminant of a quadratic equation is less than zero then it will not have any real roots.
