WebBy definition, (x,x)= {{x},{x,x}}. This last set is equal to {{x},{x}} ... Equivalence Relation, and finding the subset that defines the relation. Mostly right, which means wrong. The Transitive proof is correct. The symmetric proof is correct, but cluttered. You just have to say that: as multiplication of reals is commutative, then xy > 0 ...
What is the derivative of #f(x)=tan^-1(x)# - Socratic.org
WebAug 4, 2014 · The derivative of ex is simply ex. However, in this example, x has a coefficient, so we will need to use the chain rule. If y = e5x, then, by the chain rule, the derivative will be equal to the derivative of e5x with respect to 5x, multiplied by the derivative of 5x with respect to x. dy dx = d dx [5x] ⋅ e5x. dy dx = 5e5x.
