No. "x" is the variable. Any calculation involving a variable would be an EXPRESSION.
(X2) (X2) = X4 x squared multiplied by x squared is x raised to the 4th power.
It is t2 (t squared). Anytime you multiply a number or a variable by itself, then it is squared. If it's multiplied by itself 3 times, then it's cubed, or t3
Yes. If we don't see an exponent, the exponent is understood to be one. Just like if we don't see a sign, the sign is assumed to be positive. This in no way constricts or limits the variable. The variable can still be anything at all. But assumptions like this are part of mathematics. How tedious would it be to have to write "x1" for each x? In any case, x1 = x so it is almost pointless.Yes, because if the variable (hypothetically speaking) is 1 (and it can be any number in the world, but 1 is an example), and the exponent (power) is 1, there is only one number to multiply, therefore, the number can only be by itself. If it is squared (to the second power) then you multiply the variable against itself (in this case, 1 X 1), but if the variable doesn't have an exponent, it is assumed to be to the power of one. Take the number 2, for example. If 2 is the variable, x, and x is alone, and you multiply how big the number is of the exponent, and because there is none, it is to the first power.X squared looks like this: x X xX (a.k.a. x to the first power) looks like this: xIf there is no exponent, you only multiply what is there, which there is only one variable, so it is assumed to be to the first power. If it were squared, or to the second power as demonstrated above, you would multiply x by itself. If you count the variables in the equation, x squared has two x's, while x alone has only one x in the equation. Because there is only one x, and the exponent represents how many of that number (in this case, x) you multiply by itself, x is assumed to be to the first power, or to the power of one.
Sin squared, cos squared...you removed the x in the equation.
If you mean a2 x a2... the answer is a4
x2
It is a quadratic expression in the variable x.
(1 - cos(2x))/2, where x is the variable. And/Or, 1 - cos(x)^2, where x is the variable.
It is a quadratic equation in the one variable.
It is an expression whose value will depend on the value of the variable x.
No, actually x is the variable in mathematics. cos(x) or cosine is considered a trigonometric function with a variable x.
which is considered as dependent on the variable on x axis which is considered as independent variable in the plotting of graph
X2/X = X ======= I do not think you can divide one variable type by another.
it's the variable squared
x^2 * x^2 = x^4. When multiplying two variables with exponents, you simply have to add the exponents together, keeping the same variable. So in this case you'd add 2+2 to get a variable to the 4th power.
You can calculate a value if you assign a value to variable "x".
It is a quadratic equation in the variable x.
