can out of three constants one become variable?

no, else it wouldn't be called a constant.

Yes, but their values are dynamic, meaning their values changes in respect to the arguments passed to them. (well, you can also say that they don't have values)\n\nsin cos tan is a function, they takes an argument then return a value, they don't have a fixed value, but rather their value is determined by the argumnet given to them. This values is determined by the ratio of the sides of a right angled triangle\n\nPi is a mathematical constant, thus it have a value, i.e. 3.1415...\n\nAnother example of other mathematical function is log (logarithm). Log doesn't have a value\n\nAn example of other mathematical constant is pi and e\n\nTo Popkin: sorry, for the wrong "dynamic" mistake, English is not my first language. And dunno, please make an answer of your own, don't just copy others.

1. Move the non variable constant to the opposite side\n3x^2 - 8x = 2\n\n2. Factor out the 'a' term\n3(x^2 - 8/3x) = 2\n\n3. Take 1/2 the middle term, square it, and add it to both sides\n1/2 of 8/3 = 8/6\n3(x^2 - 8/3x + (8/6)^2) = 2 + (8/6)^2\n\n4. Factor and simplify\n3(x - 8/6)^2 = 2 + 64/36\n3(x - 8/6)^2 = 72/36 + 64/36\n3(x - 8/6)^2 = 136/36\n(x - 8/6)^2 = 136/108\n(x - 8/6)^2 = 68/54\n(x - 8/6)^2 = 34/27\nx - 8/6 = sqrt(34/27)\n\nx = 8/6 + sqrt(34/27)\nand\nx = 8/6 - sqrt(34/27)

You can.  Use the mapping (x, y, z) -> x.  Of course, that is a many-to-one mapping, and kind of useless.

The first one is (-5, 3). I don't remember how to do the others.

If you have 2 equations, just solve for one variable for one of the equations. Take that equation and plug it into the same variable for the other equation. You will solve for that variable, and plug in that number to any of the 2 equations to solve for the other variable.

i think its variable1 = (object name).text.value\nor variable1 = (object name).value, something like that, i nt very good though

Instead of  num3 = num1*num1 you need to set num3 to 1 and then MULTIPLY num3 *  num1.\n\nreplace int LoopCounter, num3; with int LoopCounter, num3 = 1;\n\nand replace num3=(num1*num1); with num3*=num1;

No, it's an independant variable (in the sense that it's not a linear combination of other variables such as length, mass, or charge) and, since it's linearly independant, it can be used as a dimension (or one of the spanning vectors) in a vector space.\n\n\nDoug

Are you asking for help or an answer?\n\nTake any 2 equations and multiply all of the terms or one or both by numbers that will make one of the terms in each equation have the same coefficient. Now subtract one from the other and the term will disappear. Now take the resulting equation and do the same with it against the third. Keep doing this until you are down to one term and solve for the variable. Now substitute the variable into the equation and solve for the other variables.

1) yes, by definition\n2) no, example: sin x on [0,2 pi]\n3) no , example |x|, absolute value of x is continuous in 0  but not differentiable in 0.\n4) yes, since (F-G)' = f-f = 0, then F-G is a constant.\n5) yes, known theorem

A variable is used when ANY number can fit into the equation.  For instance, for the speed equation (s = d/t, where s is speed, d is distance, and t is time),  any number we choose for d, and any number we choose for t will give us s.  A variable is just that, something that vaires.

infinite values for both,\nits caus u cant solve two variables with just one equation

all are possible\n\nanttderivative is x^2/2+3x +c\n1st one ok\n2nd ok ok\n3rd one x^2/2+3x + 9 ok\n4th one x^2/2+3x -8\nall differe only by a constant\n\nso all are possible

YES !!!\nA variable y is a function of x if a relation between x and y produces exactly one value of y for each value of x.\n\nThis is not a higher education question !
