## 2.2One-sided limits
Consider the function $$F(x)$$ whose graph is shown in Figure 2.2. If we take $$x$$ values closer and closer to 2.5, but less than 2.5, $$F(x)$$ gets closer and closer to 5. In other words, when $$x$$ approaches 2.5 through the values less than 2.5, $$F(x)$$ approaches ... |
1. linear differential equation
Hello
im stuck on the following differential equation. I understand since it linear we find the general solution by finding the complementary function and adding it together with a particular integral. Im stuck because in this example the RHS has both a linear function and an exponenti... |

# CLASS-4ADDITION - HORIZONTAL OR VERTICAL
Vertical addition is a method of adding two or more numbers that involves aligning them vertically and adding the digits in each column. Here are some properties of vertical addition:
1. Commutativity: The order in which the numbers are added does not affect the result. For ... |
# The real number √2 as a set
In set theory, all kinds of mathematical objects are hereditary sets: Numbers, relations, functions, etc.
Often, these mathematical objects can be constructed with sets in different ways and there is no canonical way to do it - so you may encounter different definitions in different text... |

How do you graph f(x) = 4 sin(x - pi/2 ) + 1?
1 Answer
Mar 13, 2016
You have to identify a few important elements of the graph first.
Explanation:
Amplitude: in a function of the for $y = a \sin b \left(x + c\right) + d$, the amplitude is at $| a |$. So, the amplitude is at 4. The amplitude is the distance between ... |
