In this way, the product of the functions u (x)v (x) is also differentiable and stated as (uv) = uv + uv. UCI ICS/Math 6A, Summer 2007. Times Table Boxes. Solution From X to Y, he can go in $3 + 2 = 5$ ways (Rule of Sum). Add & Subtract. Long Multiplication Steps: Stack the numbers with the larger number on top. The day counter or days calculator above can be used in situations such as counting down to a birthday, counting the number of days into a pregnancy, the number of business days left for a project, etc. The rule of product is a guideline as to when probabilities can be multiplied to produce another meaningful probability. u = f ( x) or the first multiplicand in the given problem. The total no. The headmaster is going to pick a boy and a girl at random. Given two differentiable functions, f (x) and g (x), where f' (x) and g' (x) are their respective derivatives, the product rule can be stated as, or using abbreviated notation: The product rule can be expanded for more functions. We are Going to Discuss Product Rule in Detail. Examples.
