    Sine & Cosine Graphs- someone help me with this please

    Here's the deal. I'm taking an integrated math class that I probably shouldn't, because it recommends taking Algebra 2 beforehand. I haven't taken Algebra 2. I was trying to avoid it, because, well I don't do algebra and this class isn't only about this stuff. This is just a section in it. But I...

    Path between 2 graphs

    I have 2 un-direct graphs, A and B. I know that the intersection between A and B is not empty. In detail, suppose that s and d are nodes in A and that b is a node in B. I know that some nodes in I(b) (neighbors of b) and also their edges belong to A, but NOT b. Because I am looking for a path...

    Thread: Graph Grammar Function For Two Exotic Graphs Question please.

    I will start my question by describing a particular graph. 1. There are a finite, fixed, number of nodes. labeled {A,B....Z} (so for this example there are 24 nodes). 2. Each node consists of another graph (tree) with exactly 3 nodes in 3 depths. That means we have a graph where the nodes...

    How to distinguish between these two graphs?

    Consider the two functions f(x) = x^2 and g(x) = 1/|x|. The first one is a parabola with the vertex at the origin. The second one is an absolute value function with a V-shaped graph. If you take the reciprocal of both functions, their graphs look very similar. Both have an asymptote...

    Changing the way of writing maths

    Greetings and wonderful day fellow maths enthusiasts! I'm working on something like this https://brainec.com The idea is to put 'noisy' and overwhelming research papers, scripts, notes, books and basically whole mathematics into interconnected graphs, cause... knowledge is often...

    Domain and range of restriced tan, cos and sin graphs?

    I've been told you need to restrict the domain to find the inverse functions of sin, cos and tan. I am told the following from a source: But it really bothers me because the graphs tell me something different. In case of sin x I can see that the domain on the graph is indeed what they are...

    Interesting thing about graphs (adding x! to formulas)

    I was just playing with a graph drawing software and noticed something very interesting. The graph of y = x! , when going further into negative X, turned into a straight line with infinitely long vertical lines coming out of it to both positive and negative Y at every whole number. Basically it...

    Transformations of graphs

    The graph of function f(x)=ax+b is transformed by the following sequence: A)*Translation by (1 2) *Reflection in y=0 *Horizontal stretch, scale factor 1/3 relative to x=0 The resultant function is g(x)=4-15x. Find a and b . I am not sure how to do this problem.

    How to prove graph also has a cycle of length a + b-2.

    If an undirected graph contains two cycles of lengths a, b respectively, that have exactly one edge in common. How can I prove that the graph also has a cycle of length a + b-2.
