Document Summary

A linear equation is one in which the variables are raised to the first power. The graph of a linear equation is a line. Slope a measurement of the steepness of a line which is calculated by comparing its vertical change (rise) to its horizontal change (run) Slope of a line, m = rise run m y. , x1 x2 (x1,y1) (x2, y2) rise = y2 - y1 run = x2 - x1. If x1 = x2, then the line is vertical and the slope is undefined. Equation of a vertical line: if a line goes through point (a, y) and is vertical, then the equation is given by x = a . Equation of a horizontal line: if a line goes through point (x, b) and is horizontal, then the equation is given by y = b. slope is zero. Point-slope form of the equation of a line: y - y1 = m(x - x1)

must understand functions to be able linearize. First let's review what graphs of certain functions looks like. Sketch the shape of each type of y vs. x function below. k is listed as a generic constant of proportionally. Linear y = kx Inverse y = k/x Inverse Square y = k/x^2 Power y = kx^2 You will notice that only the linear function is a straight line. We can easily find the slope of our line by measuring the rise and dividing it by the run of the graph or calculating it using two points. The value of the slope should equal the constant, k, from the equation. Finding k is a bit more challenging in the last three graphs because the slope isn't constant. This should make sense since your graphs aren't linear. So how do you calculate the constant, k? You need to transform the non-linear graph into a linear graph in order to calculate a constant slope. You can accomplish this by transforming one or both of the axes for the graph. The hardest part is figuring out which axes to change and how to change them. The easiest way to accomplish this task is to solve your equation for the constant. Note in the examples from the last page there is only one constant, but this process could be done for other equations with multiple constants. Instead of solving for a single constant, put all of the constants on one side of the equation. When you solve for the constant, the other side of the equation should be in fraction form. This fraction gives the rise and run of the linear graph. Whatever is in the numerator is the vertical axis and the denominator is the horizontal axis. If the equation is not in fraction form, you will need to inverse one or more of the variables to make a fraction. First let's solve each equation to figure out what we should graph. Then look below at the example and complete the last one, a sample AP question, on your own. State what should be graphed in order to produce a linear graph to solve for k.

Convert the above Riemann Sum to an integral by letting delta x rightarrow 0. Since this integral must be zero, we get an equation. Solve the equation for x to show that Suppose that the length of the rod is 5m and that its density is delta (x ) = (0.lx3 + 2) kg/3. Find the center of mass of the rod, and indicate where it is on a diagram. Is your center of mass to the left or right of the geometric center of the rod? Explain why this is so. The same process can be used to compute the center of mass of a 2-D object. The coordinates of the center of mass of such an object will be and . The notation used to refer to the different quantities is (the moment about the y/-axis), (the moment about the x -axis), and . Of course, M is simply the total mass of the object, represents the "vertical" line upon which the solid would balance, and represents the "horizontal" line upon which the solid would balance Therefore, the point (x, y) represents the one point at which the solid would balance perfectly. An exactly analogous set of formulas holds for 3-D objects. Find the center of mass of a lamina defined by the parabola y = 2 - 3x2 and the x-axis if its density is given by delta(x, y ) = x4 y2. For the above region, find the geometric center, and if it differs from the center of mass, explain why this is so and why it makes sense. (Hint: making a judicious choice for delta will ensure that the geometric center and the center of mass are the same point - so finding the center of mass with the above formulas and this choice of delta will actually give you the location of the geometric center of the object.) When engineers design an appliance, one of the concerns is how hard the appliance will be to tip over, when tipped, it will right itself as long as its center of mass lies on the correct side of the fulcrum, the point on which the appliance is riding as it tips. See the figure below. Suppose the profile of an appliance of approximately constant density is parabolic (y = a ( l - x2)), like an old-fashioned radio. What values of a will guarantee that the appliance will have to be tipped more than 45 degree to fall over? Your answer should be exact.
