Second moment method

In mathematics, the second moment method is a technique used in probability theory and analysis to show that a random variable has positive probability of being positive. More generally, the "moment method" consists of bounding the probability that a random variable fluctuates far from its mean, by using its moments. The method is often quantitative, in that one can often deduce a lower bound on the probability that the random variable is larger than some constant times its expectation. The method involves comparing the second moment of random variables to the square of the first moment. (Wikipedia).

Newton's 2nd Law (1 of 21) Calculate Acceleration w/o Friction, Net Force Horizontal

Shows how to use Newton's Second Law of motion to calculate the acceleration of an object. The acceleration of an object is directly proportional to the net force applied to the object and inversely proportional to the mass of the object. The second law can also be stated in terms of an ob

C02 Reduction of order

The first method for solving second order linear ODE's uses reduction in order. In this method the second derivative is reduced to a first derivative in the dependent variable, which can usually be solved by separation of variables, or by introduction an integrating factor.
