### Why do you need total derivative and partial derivative?

The partial derivative only acts on one the variables on the equations and treats the others as constant.

### What is a partial derivative?

A partial derivative is the derivative of a function of more than one variable with respect to only one variable. When taking a partial derivative, the other variables are treated as constants. For example, the partial derivative of the function f(x,y)=2x2 + 3xy + y2 with respect to x is:?f/?x = 4x + 3yhere we can see that y terms have been treated as constants when differentiating.The partial derivative of f(x,y) with respect to y is:?f/?y = 3x + 2yand here, x terms have been treated as constants.

### What is the difference between partial derivative and derivative?

Say you have a function of a single variable, f(x). Then there is no ambiguity about what you are taking the derivative with respect to (it is always with respect to x). But what if I have a function of a few variables, f(x,y,z)? Now, I can take the derivative with respect to x, y, or z. These are "partial" derivatives, because we are only interested in how the function varies w.r.t. a single variable, assuming that the other variables are independent and "frozen". e.g., Question: how does f vary with respect to y? Answer: (partial f/partial y) Now, what if our function again depends on a few variables, but these variables themselves depend on time: x(t), y(t), z(t) --&gt; f(x(t),y(t),z(t))? Again, we might ask how f varies w.r.t. one of the variables x,y,z, in which case we would use partial derivatives. If we ask how f varies with respect to t, we would do the following: df/dt = (partial f/partial x)*dx/dt + (partial f/partial y)*dy/dt + (partial f/partial z)*dz/dt df/dt is known as the "total" derivative, which essentially uses the chain rule to drop the assumption that the other variables are "frozen" while taking the derivative. This framework is especially useful in physical problems where I might want to consider spatial variations of a function (partial derivatives), as well as the total variation in time (total derivative).

### What is the difference between the differentiation of the function and the partial differentiation of the function?

You can differentiate a function when it only contains one changing variable, like f(x) = x2. It's derivative is f'(x) = 2x. If a function contains more than one variable, like f(x,y) = x2 + y2, you can't just "find the derivative" generically because that doesn't specify what variable to take the derivative with respect to. Instead, you might "take the derivative with respect to x (treating y as a constant)" and get fx(x,y) = 2x or "take the derivative with respect to y (treating x as a constant)" and get fy(x,y) = 2y. This is a partial derivative--when you take the derivative of a function with many variable with respect to one of the variables while treating the rest as constants.

### What is this symbol s with a d backwards?

It is likely the symbol for the partial derivative, ∂, often used in mathematics to denote differentiation with respect to one variable while treating others as constants.

### Definition of partial differential equation with example?

A partial derivative is the derivative in respect to one dimension. You can use the rules and tricks of normal differentiation with partial derivatives if you hold the other variables as constants, but the actual definition is very similar to the definition of a normal derivative. In respect to x, it looks like: fx(x,y)=[f(x+&Delta;x,y)-f(x,y)]/&Delta;x and in respect to y: fy(x,y)=[f(x,y+&Delta;y)-f(x,y)]/&Delta;y Here's an example. take the function z=3x2+2y we want to find the partial derivative in respect to x, so we can use basic differentiation techniques if we treat y as a constant, so zx'=6x+0 because the derivative of a constant (2y in this case) is always 0. this applies to any number of dimensions. if you were finding the partial in respect to a of f(a,b,c,d,e,f,g), you would just differentiate as normal and hold b through g as constants.

### What does partial mean?

Partial in mathematics can refer to:Partial derivatives (derivative of a function with respect to a specific variable, others being held constant)A partial functionPartial can also refer to the regular English usage (referring to an isolated part of the whole).

### How do you you say view in Italian?

"Vista" is an Italian equivalent of "view."Specifically, the Italian word is a feminine singular noun. Its singular definite article is "la" ("the"). Its singular indefinite article is "una" ("a, one").The pronunciation is "VEE-stah."

### What is the derivative of x?

The derivative is 2x based on the power rule. Multiply the power by the coefficient of x then drop the power by one.

### What is the Italian translation of 'a partial amount'?

Un importo parziale is an Italian equivalent of the English phrase "a partial amount."Specifically, the masculine singular indefinite article un means "a, one." The masculine noun importo means "amount, sum." The feminine/masculine adjective parzialemeans "partial."The pronunciation is "eem-POHR-toh pahr-TSYAH-leh."
