Calculus
The branch of mathematics that deals with the study of continuously changing quantities, with the use of limits and the differentiation and integration of functions of one or more variables, is called Calculus. Calculus analyzes aspects of change in processes or systems that can be modeled by functions. The English physicist, Isaac Newton, and the German mathematician, G. W. Leibniz, working independently, developed calculus during the 17th century.

How do you work out x plus 11 equals 13?
X + 11 = 13.
Subtract 11 from both sides
X + 11 - 11 = 13 - 11
X = 2
Is the graph of a curve a function?
The graph if a function can be a curve, but it can also be any one of a ton of other shapes.
4 more units, making 7 units in total.
What do you think is true of the square roots of a complex number?
I posted an answer about cube roots of complex numbers. The same info can be applied to square roots. (see related links)
It's called a vector
∫ f'(x)/√(a2 - f(x)2) dx = arcsin(f(x)/a) + C
C is the constant of integration.
Negative ten fifths over 18 plus x equals?
That's going to depend completely on the value of 'x', and every time 'x' changes,
the value of that expression also changes.
Whatever 'x' happens to be at the moment, your expression is [ - 2 / (18+x) ].
What is 2 over X plus 1 over Y simplified they are fractions?
I understand you want [(2/x) + (1/y)] as a single fraction. The common denominator is (xy):
2/x = (2y)/(xy); and 1/y = x/(xy), so the answer is (2y + x) / (xy)
What are the two values you need to determine velocity?
You need to know your change of position vs. change of time.
What is the y-intercept of x equals 8?
The graph of [ x=8 ] is a vertical line through the point 8 on the x-axis.
It never touches the y-axis, and has no y-intercept.
Would you please factor 4x squared minus 2x minus 12?
(2x - 4)(2x + 3)
The key is to look for all the factor pairs of 12.
It's a word. It is not a number because you can't count to it.
