**Important Notes on Sin2x**

- The important formula of sin2x is sin2x = 2 sin x cos x and sin2x = (2tan x)/(1 + tan
^{2}x) - The formula for sin^2x is sin^2x = 1 - cos^2x and sin^2x = (1 - cos2x)/2.
- Sin2x formula is called the double angle formula of the sine function.

sin X = **b / r** , csc X = r / b. tan X = b / a , cot X = a / b. cos X = a / r , sec X = r / a.

The signs in each quadrant. coördinate? y, because **sin θ = y/r**, and r is always positive.

**sin θ = Opposite Side/Hypotenuse**. **cos θ = Adjacent Side/Hypotenuse**. **tan θ = Opposite Side/Adjacent Side**. **sec θ = Hypotenuse/Adjacent Side**.

The different types of irrigation include- **sprinkler irrigation, surface irrigation, drip irrigation, sub-irrigation and manual irrigation**.

Acidity Trend #2: **The More “Polarizable” The Atom, The Better It Is Able To Stabilize Negative Charge**. High charge densities tend to be less stable than low charge densities. The more “spread out” a charge can be, the more stable it will be.

Some of the factors which affect the polarization at an electrode include the **viscosity of the electrolyte**, material's insolating layer, charge or discharge rate etc.

The fundamental condition of perfect competition is that **there must be a large number of sellers or firms**. Homogeneous Commodity is the second fundamental condition of a perfect market. The products of all firms in the industry are homogeneous and identical.

The **border-color** property is used to set the color of the four borders. The color can be set by: name - specify a color name, like "red" HEX - specify a HEX value, like "#ff0000"

**Equilibrium is a pretty easy topic** - big name, but easy idea. First, when you have a system made up of a bunch of molecules, those molecules sometimes combine. That's the idea of a chemical reaction. Second, a chemical reaction sometimes starts at one point and moves to another.

PageRank (PR) is **an algorithm used by Google Search to rank web pages in their search engine results**. It is named after both the term "web page" and co-founder Larry Page. PageRank is a way of measuring the importance of website pages.

**Find the angle of elevation of the plane from point A on the ground.**

- Step 1 The two sides we know are Opposite (300) and Adjacent (400).
- Step 2 SOHCAHTOA tells us we must use Tangent.
- Step 3 Calculate Opposite/Adjacent = 300/400 = 0.75.
- Step 4 Find the angle from your calculator using tan
^{-}^{1}

In this tutorial, we will learn what algorithms are with the help of examples. In computer programming terms, an algorithm is **a set of well-defined instructions to solve a particular problem**. It takes a set of input and produces a desired output.

**Types of Communications Internet Protocols (IP)**

- Transmission Control Protocol (TCP) – used for data transmission.
- User Datagram Protocol (UDP) – used by programs to send short datagram messages.
- Internet Control Message Protocol (ICMP) – messages used for diagnostic or error-generating purposes.

1 Answer. The correct option is (C) **Noise**. Explanation: Noise is not a component of communication system.

**At a glance: The different types of accounting**

- Financial accounting.
- Governmental accounting.
- Public accounting.
- Cost accounting.
- Forensic accounting.
- Management accounting.
- Tax accounting.
- Auditing.

**Try to take one CAT mock every week in the initial months (6 to 4 months before CAT)**. Gradually increase the number of attempts. In the last month, you should be solving one mock every 2 days, one allocated to solving the mocks and the next day for analysis of the mock.

They are **writing numbers up to 1,000 and comparing numbers**. They are also building their mental math skills by solving problems mentally. Encourage your child to: Read numbers out loud and record numbers you say verbally. Practice understating place value by deciding what the value of a digit is in a specific number.

Polarization is a defect that occurs in simple electric cells **due to the accumulation of hydrogen gas around the positive electrode**. In local action, embedded impurities in a zinc electrode can act as positive electrodes and create electric currents between zinc and this positive electrode.
