The heart of the wave equations as David described them are trigonometry functions, sine and cosine. Trig functions take angles as arguments. The most natural units to express angles in are radians. The circumference of a circle = π times its diameter. The diameter is 2 times the radius, so C = 2πR. Now when the radius equals 1, C = 2π.Zeros and multiplicity. When a linear factor occurs multiple times in the factorization of a polynomial, that gives the related zero multiplicity. For example, in the polynomial f ( x) = ( x − 1) ( x − 4) 2 , the number 4 is a zero of multiplicity 2 . Notice that when we expand f ( x) , the factor ( x − 4) is written 2 times.One use in math is that if f" (x) = 0 and f"' (x)≠0, then you do have an inflection point. Unfortunately, there are cases where f"' (x)=0 that are inflection points so this isn't always useful, but if the third derivative is easy to determine (e.g. for a polynomial) then it …Explanation: We can determine if a function is differentiable at a point by using the formula: lim h→0 [ (f (x + h) − f (x)) / h]. If the limit exists for a particular x, then the function f (x) is differentiable at x. We can also tell if a function is differentiable by looking at its graph. The function has a sharp edge at that point.Are you in need of graph paper for your next math assignment, architectural design, or creative project? Look no further.

It curves back up and passes through the x-axis at (two over three, zero). Where x is less than negative two, the section below the x-axis is shaded and labeled negative.The same applies to the vertical extent of the graph, so the domain and range include all real numbers. Figure 18 For the reciprocal function f(x) = 1 x, f ( x) = 1 x, we cannot divide by 0, so we must exclude 0 from the domain. Further, 1 divided by any value can never be 0, so the range also will not include 0.Fortunately, the second derivative can be used to determine the concavity of a function without a graph or the need to check every single x-value. It is for this reason that given some function f(x), assuming there are no graphs of f(x) or f'(x) available, the most effective way to determine the concavity of f(x) is to use its second derivative.Fortunately, the second derivative can be used to determine the concavity of a function without a graph or the need to check every single x-value.
