Gradient Boosting using Automatic Differentiation
03 Sep 2016
Today, we’ll close our exploration of Gradient Boosting. First, we looked into a simplified form of the approach, and saw how to combine weak learners into a decent predictor. Then, we implemented a
very basic regression tree. Today, we will put all of thi... | 5 | [

How do you differentiate f(x)= 7xsinx using the product rule? | HIX Tutor
How do you differentiate #f(x)= 7xsinx# using the product rule?
Answer 1
$f ' \left(x\right) = 7 \sin x + 7 x \cos x$
According to the product rule:
#f(x) = g(x)h(x) -> f'(x) = g'(x)h(x)+g(x)h'(x)#
So for #f(x) = 7xsinx# we can take:

Calculus about volume of sphere rate of change can someone help me?
The ball made of ice is melting at at rate 2 ft^3
So dV/dt = -2
Volume of the sphere is V = 4/3× ∏ × r^3
dV/dt = 4/3 × ∏ ×3 × r^2 × dr/dt
Since r = 20 inches
= 20/12 = 5/3 ft
Now -2 = 4/3 × ∏ ×3 × (5/3)^2 × dr/dt

In the above figure, each slice has the shape of a washer so its area equals the area of the entire circle minus the area of the hole. where R is the outer radius (the big radius) and r is the radius
of the hole (the little radius). Multiply this area by the thickness, dx, ... | 4 | [

Abstract Algebra
Theorem 8.5
Return to Theorems, Glossary, Homework Problems.
Statement:
Let $A$ be a nonempty set, and let $S_A$ be the collection of all permutations of $A$. Then $S_A$ is a group under permutation multiplication.
Proof:
Through previous examples (Example 8.4), we have shown that the composition ... | 4 | [
