BX) = b5 * V(X) = σ5bX Proof is below 15 V(X ±11 Logical Operations Mathematics typically involves combining true (or hypothetically true) statements in various ways to produce (or prove) new true statements We begin by clarifying some of these fundamental ideas By a sentence we mean a statement that has a definite truth value , true (T) or false (F)—for example, More generally, by aThe chain rule for this case is, dz dt = ∂f ∂x dx dt ∂f ∂y dy dt d z d t = ∂ f ∂ x d x d t ∂ f ∂ y d y d t So, basically what we're doing here is differentiating f f with respect to each variable in it and then multiplying each of these by the derivative of that variable with respect to t t
In similarity with a line on the coordinate plane, we can find the equation of a line in a threedimensional space when given two different points on the line, since subtracting the position vectors of the two points will give the direction vector Q = ( − 3, 0, 1) Q= (3,0,1) Q = (−3,0,1)Example 3SAT formula (x y z)(x y z)(x y z)(x y z) 37 kSAT Facts Every boolean formula has an equivalent CNF formula But the size of the CNF formula may be exponential in the size of the original Not every boolean formula has a kSAT equivalentDefinition Let X,Y,Z be jointly distributed according to some pmf p(x,y,z) The conditional mutual information between X,Y given Z is I(X;YZ) = − X x,y,z p(x,y,z)log p(x,yz) p(xz)p(yz) (32) = H(XZ)−H(XYZ) = H(XZ)H(YZ)−H(XYZ)−H(Z) The conditional mutual information is a measure of how much uncertainty is shared by X and Y
