What are the critical numbers of 3 cos x?
Maximum = 3Minimum = -3 y - intercept = 3x - intercepts (roots) = (1/2+k)*pi radians, where k is an integer.Maximum = 3Minimum = -3 y - intercept = 3x - intercepts (roots) = (1/2+k)*pi radians, where k is an integer.Maximum = 3Minimum = -3 y - intercept = 3x - intercepts (roots) = (1/2+k)*pi radians, where k is an integer.Maximum = 3Minimum = -3 y - intercept = 3x - intercepts (roots) = (1/2+k)*pi radians, where k is an integer.
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.
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.
Why are angles important?
Angel's are very important in Islam as, they have a height status than any other of Allah's creation. angels are made out of light and they do not need food drink nor do they get tiered as they do not desire anything. the are continuesly wprshipping Allah's commands. Angels carry out various tasks, each angel has different tasks there for thwey have different powers. it is iportant to believe in angels as Muslims are taught this in the quran and sunah, when a Muslim believe in Allah it fardz to believe in his angels as it is one of the pirncipal beiliefe in Islam. * * * * * The answer, although interesting, is about angels, not angles which is what the question was about! Geometry has its roots in ancient people trying to measure plots of land which were flooded annually by the Nile. When the flood waters receded, land had to be restored to its former owners and it was important to know how much land each landowner had before the flooding. The likelihood that taxes were partly based on the area of land owned made it particularly important to get the calculations right. The areas of some shapes are relatively simple to calculate from the lengths of their sides but for some shapes it is easier if angles (and their trigonometric ratios) can be used in the calculations.
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 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.
What roots of the quadratic equation are equivalent to xx-x-12 equals 0?
-4,3 are the roots of this equation, so for the values for which the sum of roots is 1 & product is -12
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.
