What is zero times zero - Mathematics Stack Exchange What is zero zeros? What are no nothings? From a mathematical point of view it would be my thing, but none of us are educated that much in math, so I am curious to hear an expert opinion
A coin is flipped 8 times: number of various outcomes A coin is flipped eight times where each flip comes up either heads or tails How many possible outcomes a) are there in total? b) contain exactly three heads? c) contain at least three heads? d)
Vector cross product identity for $(a\\times b)\\cdot(c \\times d)$ It might be helpful if you first introduce a new symbol to refer to one of the vector cross-products as a whole E g , let's define (a × b) =: x (a × b) =: x Using the cyclic property of the scalar triple product, we equate the scalar quadruple product to the dot-product of one of the vectors with the vector triple product of the other three:
