In the context of mathematics and physics, "b" and "h" are often referred to as variables because they represent quantities that can change or vary. For example, in geometry, "b" might represent the base of a shape, while "h" could denote its height. These variables are used in equations to model relationships and solve problems, allowing for a range of possible values depending on the specific context.
they are letters in math like algerbra example AxA=b
Let's call the parallel sides A and B, and the distance between them as H. The area of the trapezium, or K, is (A+B)H/2. K = (A+B)H/2

(b+h)(b+h)= b2+2hb+h2.
b/h
In the German note naming system, believe it or not, H major DOES exist, because what they call H we call B (natural) and what they call B we call B (flat).
H is what the Germans call the note B. B is what they call B-flat. That is why Bach could spell out his name in notes... Bflat-A-C-B.
A b***h

A and b are the variables cause they represent a number

Area of a parallelogram = b*h. Call the area of parallelogram one x and two y. We now know that x = y = b(x)h(X) = b(x)h(y). Now b(x)h(x) = b(x)h(y) b(x)h(x)/b(x) = b(x)h(y)/b(x) h(x) = h(y), so the height of the second parallelogram must equal the height of the first.
Use a temporary variable. Example (swap variables "a" and "b"): int a = 5; int b = 10; // Swap the variables int temp; temp = a; a = b; b = temp; System.out.println("a = " + a); System.out.println("b = " + b);Use a temporary variable. Example (swap variables "a" and "b"): int a = 5; int b = 10; // Swap the variables int temp; temp = a; a = b; b = temp; System.out.println("a = " + a); System.out.println("b = " + b);Use a temporary variable.

Because there are only 7 notes. Actually in German music - the note which we call B is called "H" and the note Bb is called "B".
Actually, there is! German music uses letters A-H instead of A-G, it's not that there are different notes, it's just that the note they call B is actually a Bb, and H is the same as B natural.
H this is so Bach would be able to spell his names in his songs some still call it H.
