An important goal of many multi-mic sound capture devices is to provide a directional signal to noise ratio improvement, while consuming as little power as possible. Acoustic Beamforming of signals in the audible hearing range (20 Hz to 20kHz), requires a time domain fractional delay FIR filter applied to each micropho... | {} |

Gradient Descent in Machine Learning. Gradient descent is an optimization algorithm used for minimizing the cost function in various ML algorithms. Gradient descent optimization is considered to be an important concept in data science. We have partly discussed recurrent neural network (RNN) when stu... | {} |

## Description
Here comes the problem: Assume the sky is a flat plane. All the stars lie on it with a location (x, y). for each star, there is a grade ranging from 1 to 100, representing its brightness, where 100 is the brightest and 1 is the weakest. The window is a rectangle... | {} |
# Which inequality should I apply?
Algebra Level 3
$\large\frac x{2x+y+z} + \frac y{x+2y+z} + \frac z{x+y+2z}$
Let $$x,y$$ and $$z$$ be positive numbers. Find the maximum value of the expression above.

# How do you solve the inequality 3 (y - 9) > 15 + 3w?
May 18, 2018
$y > w + 14$
$y - 14 > w$
#### Explanation:
Let's start by distributing the $3$ on the left side. Doing this, we get
$3 y - 27 > 3 w + 15$
Let's add $27$ to both sides to get
$3 y > 3 w + 42$
Let's divide all terms by $3$ to get
$y > w + 14$

# Special Relativity - Finding the angle θ measured in the frame S
[Question] Frame $$S'$$ moves with velocity $$V$$ in the $$x$$-direction relative to frame $$S$$. A rod in the frame $$S'$$ lying on the $$x'-y'$$ plane makes an angle $$\theta'$$ with respect to the forward direction of motion.

While Table $$\PageIndex{1}$$ provides the pKa values of only a limited number of compounds, it can be very useful as a starting point for estimating the acidity or basicity of just about any organic molecule. It then can be titrated using a solution in glacial acetic acid of a very strong acid, such as perchloric acid... | {} |
