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.

2Y equals X plus 4 in a graph?
2y = x + 4
Divide each side by 2:
y = (1/2)x + 2
The graph is a straight line with a slope of (1/2) and a y-intercept of 2.
How do you solve 8x plus 14 - 7x equals 2 using like terms?
Re-arrange it: 8x - 7x + 14 = 2
ie x + 14 = 2
Subtract 14 from each side: x = -12
The answer is 398.78 cm (approx.). Inches and centimeters are both units of linear measurement. Inches are used in the imperial system whereas centimeters are used in the metric system. To convert from inches to cm, multiply the inch unit by 2.54.
Solve the system using elimination 3x -9y equals 3?
Solving equations in two unknowns requires two independent equations. Since you have only one equation there is no solution.
What is area for 9' x 5' x 10'?
If that's a rectangular block, you have to use the formula for a rectangle, and add all six sides to get the surface area; since opposite sides are equal, you can group them like this: 2 x 9 x 5 + 2 x 9 x 10 + 2 x 5 x 10.
How do you create a table of values for each rule with at least four values for x?
For each rule draw a table with 5 rows and 2 columns. At the top of each table write a caption denoting which rule applies to that particular table. In the top row of each table write the letter "X" in the first column and the letter "Y" in the second column.
Now for each table in the first column in rows 2,3,4, and 5 write the values of X that apply to the experiment.
Now apply the rule for each value of X for a particular table (particular rule) and write the value of Y (obtained by observation or calculation) in the corresponding column
What is 2x squared plus 5x minus 3 multiplied by plus x minus 2?
(x-2)*(2x2+5x-3)
Multiply out the brackets term by term taking care with the minus terms:-
2x3-4x2+5x2-10x-3x+6
Collect like terms:-
Answer: 2x3+x2-13x+6
What is 5x squared over x times 20 squared?
You need to clarify your question. Depending on what you mean, the answer could be:
- x2/16
- 2000x
- x/80
or many other things.
You cannot, since "x equals 0" and "y equals 0" are NOT inequalities!
If x and y are counts of things, or measures (such as length) which must be positive then the reason for such constraints should be obvious.
What does 3 radical 2 plus 4 radical 2 equal?
first the two numbers have the same radicand which is radical 2 so we just
add the numbers before them to become 7 radical 2
What is sec squared x times csc x divided by sec squared x plus csc squared x?
Ah, secant, annoying as always. Why don't we use its definition as 1/cos x and csc as 1/sin x? We will do that
Also, please write down the equation, there is at least TWO different equations you are talking about.
x^n means x to the power of n
1/(sin x) ^2 is csc squared x, it's actually csc x all squared
1/(cos x) ^2 in the same manner.
Which equation is equivalent to 2x plus 7 equals 3?
2x+7=3 is an equation. However,
2x=-4 is equivalent. So is
x=-2.
And an infinite number of others.
What is csc A if cos A equals 0.6?
cos A=3/5
sin=square root of (1-cos2)
sin=square root of (1-3/52)
sin=square root of (1-9/25)
sin=square root of (16/25)
sin=4/5
csc=1/sin
csc=1/(4/5)
csc=5/4
