Differentiating mult-variable equation

In summary, a mult-variable equation contains more than one variable and is solved by manipulating the equation using algebraic rules. Differentiating a mult-variable equation helps find the rate of change between variables and is commonly used in fields such as physics, economics, and engineering. The product rule, chain rule, and implicit differentiation are common techniques for differentiating mult-variable equations. These equations have various applications in science, including modeling complex systems and understanding natural phenomena in areas such as physics, chemistry, biology, and engineering.

Any ideas for solving this, I am having trouble using implicit differentiation along with using log differentiation, thanx!:

x^3 + x tan^-1 y = e^y

Differentiate w.r.t x

[tex]\frac{df(y)}{dx}=\frac{df(y)}{dy}\frac{dy}{dx}[/tex]

In other words, the derivative of y with respect to x is:


3x2+ tan-1y+ xy'/(1+ y2)= eyy'. Now solve for y'.

I see no reason to use "logarithmic differentiation".
 

1. What is a mult-variable equation?

A mult-variable equation is an equation that contains more than one variable, each of which represents a different quantity. These variables are usually represented by letters and can have different values, making the equation more complex than a single-variable equation.

2. How do you solve a mult-variable equation?

To solve a mult-variable equation, you need to manipulate the equation using algebraic rules to isolate one variable at a time. This involves combining like terms, using inverse operations, and distributing terms. Once you have isolated all of the variables, you can solve for their values by substituting them back into the original equation.

3. What is the purpose of differentiating a mult-variable equation?

The purpose of differentiating a mult-variable equation is to find the rate of change of one variable with respect to another. This can help us understand how changes in one variable affect the other variables in the equation. Differentiation is often used in fields such as physics, economics, and engineering to model real-world situations.

4. What are some common differentiation techniques for mult-variable equations?

Some common differentiation techniques for mult-variable equations include the product rule, chain rule, and implicit differentiation. These techniques allow us to differentiate more complex equations by breaking them down into simpler parts. It is important to understand these techniques and when to use them in order to effectively differentiate mult-variable equations.

5. What are some applications of mult-variable equations in science?

Mult-variable equations have a wide range of applications in science, including physics, chemistry, biology, and engineering. They are used to model complex systems and relationships between multiple variables, such as the motion of objects, chemical reactions, and biological processes. Mult-variable equations also play a crucial role in understanding and predicting the behavior of natural phenomena, making them a valuable tool for scientists.
