How do you find antiderivatives, or indefinite integrals, using basic integration rules? Integration by Parts… How? If there was a constant multiplied in front of the x-power, you can keep the constant and integrate the rest of the term Constant Multiple Rule.

What makes an equation linear? Simple Definition of Linear Equation: An equation that forms a straight line on a graph. More precisely, a linear equation is one that is dependent only on constants and a variable raised to the first power.

Linear equations can always be manipulated to take this form: Linear equations are often written with more than one variable, typically x and y. Such equations will have many possible combinations of x and y that work.

When those points known as coordinate pairs are plotted on an x-y axisthey will form a straight line. Let's take a look at this graphically below. The two equations drawn are linear. How do I know if an equation is linear? Does the equation or function include any squared terms?

How about other terms with exponents other than 1 or, technically, zero? If the function has no terms with an order higher than 1 a fancy way of saying exponent then it is linear!

What if it has a log or trig function, etc.? These are not linear terms.

Simply, they aren't constants regular numbers or variables with an exponent of 1, so the function isn't linear. Of course, if you haven't covered these concepts in your class yet, don't even worry about it.

So, how do I solve a linear equation? Some linear equations are really, really easy to solve. What about this one: But this rather trivial example does show us that linear equations can be quite simple, and also shows us our goal: Taking it a tiny step forward: Solving any linear equation is just a matter of performing operations on both sides of the equals sign until the equation is in the form you want usually solved for a single variable, like X or Y.

The steps are shown in detail below: Fortunately with linear equations, the steps are always relatively straightforward. There's no one way to do it, and with time you'll be able to think through a linear equation without really having to write down every step.

Try the following approach to solve the equations and see if it works for you: Collect like terms -- this means to gather all the x's together, all the y's together, and all the regular numbers known as constants and add them up separately.Consumption is the sole end and purpose of all production — Adam Smith 1.

Introduction Solving the Euler Equation: Log Utility In order to get an explicit solution for consumption, we need to specify a functional form for the utility function u(c).

A common choice is the logarithmic function: u(c) = logc. Systems of Linear Equations rewrite the unknowns or arithmetic operators. Once the augmented matrix is reduced to upper triangular form, the corresponding system of linear equations can be solved by back substitution, end end This algorithm requires approximately 2 3 n.

In this tutorial we will be looking at logarithmic functions. In some cases you will have an equation written in log form and need to convert it to exponential form and vice versa. So, when you are converting from log *Rewrite as 10 to the -3rd power.

If we re-write this equation as. y=2 x 1 2 +1, which are the mathematical inverse of raising to some power, we can use logarithms to change this equation into the form of a line. Recall that all logarithms have the properties such that log.
