exponential function - Find equation to fit data with plateau ...
网页2017年10月31日 · 3. You can fit. y = M(1 −e−ax) y = M (1 − e − a x) where M M is the maximum at which the plateau ends up and a a governs how fast it gets there. You can probably get Excel to find the best values of M M and a …

Why do parabolas' arms eventually become parallel?
网页2016年9月6日 · All parabolas are the same shape, no matter how big they are. Although they are infinite, meaning that the arms will never close up, the arms will eventually become parallel. Now, I have an argument against it. Let f(x) = ax2 + bx + c be a quadratic polynomial with a, b and c being real numbers and a ≠ 0. So, its graph will give us a …
graphing functions - How does the log axis on a semilog plot work ...
网页2020年6月5日 · This is particularly confusing to me since the difference between 2 values should increase as the exponent becomes larger. However, the distances between the intervals on the graph decrease as the exponent increases. Why is there a repeated cycle of gradually-decreasing-in-the-length-of-the-intervals between y=10^x and y=10^(x+1)?

S Curve shapes with flat middle - Mathematics Stack Exchange
网页You can do this by adding two of what you call an "S-curve": y = 1 1 +eB1−x + 1 1 +eB2−x. y = 1 1 + e B 1 − x + 1 1 + e B 2 − x. The coefficients B B in your expression and B1 B 1 and B2 B 2 in mine are not the steepness of the curve; they control where on the x x -axis the rise occurs. You can introduce variable steepnesses A1 A 1 and ...
What is the breakpoint of a piecewise function?
网页2019年2月14日 · 1. Your function is defined piecewise. The break points are wherever one of the pieces ends and the next begins. Here, the first piece is defined for x ≤ − 1, so this piece ends and x = − 1, and the next piece is defined for − 1 <x <1, so this piece ends at x = 1. You could then say that the break points are where the function is broken ...

网页I need to model the solar radiation incident on a solar panel. I tried using $$\tanh(b*(x-a))-\tanh(b*x)$$ but it does not give me a lot of flexibility with the characteristics of the curve, namely
calculus - Definition of local maxima, local minima - Mathematics …
网页A real-valued function f defined on a real line is said to have a local (or relative) maximum point at the point x∗, if there exists some ε> 0 such that f(x∗) ≥ f(x) whenever |x −x∗| <ε. The value of the function at this point is called maximum of the function. Similarly, a function has a local minimum point at x∗, if f(x∗) ≤ ...
