Use MATLAB to write a function that takes inputs R, L, C, TO, Tf, DeltaT and f and produces as output the charge on the capacitor in a driven RLC series circuit where the input voltage source is v(t) = cos(21 ft). Here f is the frequency of the voltage source in Hz. This function returns the inverse Laplace Transform of (1) L (s2 + 2) ($2 + 2as +B) where a = # and B = Lc. Note that...

Observe that the point (1,1,1) satisfies the equation 2. Although we may not be able to write down a formula for z in terms of x and y there is a function z(x,y) that has continuous partial derivatives, is defined for (x,y) near (1,1), and for which z(1,1)-1. For this function find the values of the partials дг/дх (1,1) and дг/ду (1,1). Use this to approximate z(1.1 ,.9). Finally, find az/0x (1,1). If we try to do similar calculations for...

For this problem, you must use Excel to perform the
necessary calculations. Below are the formulas and equations you
will need to use.
If it is appropriate to use the binomial distribution, use the
formula =binom.dist(number_s,trials,probability,cumulative) to
calculate the probability. In this formula, number_s is the number
of successful trials, trials is the total number of trials,
probability is the probability for a single trial expressed as a
decimal, and cumulative should be set as false. This will report
the...

Excel Lab 2: Regression and Goal Seek In this lab, you will use Excel to determine the equation of the model which best fits a set of ordered pairs obtained from data sets. You will enter data, graph the data, find the equation for the regression model, and then use that equation to make predictions for the dependent variable. You will use the goal seek to make predictions for the independent variable. Then you will consider how accurate your predictions...
