  1. Apply definite integral to investigate the area under or between curves and volume of revolution.

 

 

  1. Represent complex numbers on the complex plane in rectangular and polar form (including real and imaginary numbers), and explain why the rectangular and polar forms of a given complex number represent the same number.

 

 

 

  1. Sketch the complex number on argand diagram.

 

 

 

  1. Perform multiplication and division in complex number by converting into trigonometric form. Use De Moivre’s rule to find the higher powers. Find the nth root of the complex number in trigonometric form.

 

 

 

  1. Differentiate between polar coordinates and rectangular coordinates. Use modulus and argument to convert polar equation into rectangular equation and vice versa.

 

 

 

  1. Represent data on the coordinate plane (bar chart, histograms, and frequency polygon) or as pie chart. .

 

 

 

  1. Apply statistics appropriate to the shape of the data distribution to compare center (median, mean) and spread (standard deviation) of two or more different data sets. Interpret differences in shape, center, and spread in the context of the data sets, accounting for possible effects of extreme data points (outliers).

 

 

 

  1. Describe events as subsets of a sample space (the set of outcomes) using characteristics (or categories) of the outcomes, or as unions, intersections, or complements of other events (“or,” “and,” “not”).

 

 

 

  1. Recognize that two events A and B are independent if the probability of A and B occurring together is the product of their probabilities, and use this characterization to determine if they are independent.

 

 

 

  1. Recognize the conditional probability of A given B as P(A and B)/P(B), and deduce independence of A and B as saying that the conditional probability of A given B is the same as the probability of A, and the conditional probability of B given A is the same as the probability of B.

 

 

 

  1. Recognize and explain the concepts of conditional probability and independence in everyday language and everyday situations. For example, compare the chance of having lung cancer if you are a smoker with the chance of being a smoker if you have lung cancer.

 

 

 

  1. Discover the conditional probability of A given B as the fraction of B’s outcomes that also belong to A, and interpret the answer in terms of the model.

 

 

 

 

  1. Apply the Addition Rule, P(A or B) = P(A) + P(B) – P(A and B), and interpret the answer in terms of the model. Discover that in mutually exclusive event P(A and B) will be zero.

 

 

 

  1. Apply fundamental counting principle, permutations and combinations to compute probabilities of compound events and solve problems.
