Microsoft Mathematics 4.0 provides a fantastic set of mathematical tools that help students get school work done quickly and easily. With this free tool, students can learn to solve equations step-by-step while gaining a better understanding of fundamental concepts in pre-algebra, algebra, trigonometry, physics, chemistry, and calculus. The software also includes a full-featured graphing calculator that’s designed to work just like a handheld calculator. Additional math tools help you evaluate triangles, convert from one system of units to another, and solve systems of equations!!!

For starters, I tried differentiating Sin A:

Plotting an equation y = ax² + bx + c

Triangle solver helps you find the third angle, or side, or both

Do anything you want to do with matrices.

And guess what? For every problem it solves, it will give you the steps:

You can convert various units effortlessly.

You can use it to solve a system of up to 6 equations!!

You can even plot a three dimensional equation! Here is how I plotted the equation of the sphere x² + y² + z² = 4

A gallery is a collection of images.

After reading this post, you will learn to display images as shown below.

Gallery can be easily implemented in WordPress with the help of  “NextGen Gallery”  Plugin. I have explained in detail about its installation, uploading images, displaying gallery etc in this post.

Lets start with installing the gallery plugin.

Go to Plugins-> Add New

Search for “nextgen gallery” . The search result will be as given below. Now, Install NextGen Gallery .

Click Install.

After the installation, activate the Plugin.

Now, you can see a new Gallery option in your Dashboard.

Goto Add Gallery/ Images. Give a name to your gallery( as i gave Gallery1). and then click Add Gallery.

This will create a gallery named Gallery1.

Now lets see how to upload images. Click  Upload Images option to upload images.

Browse for images. You can select multiples images at a time using Ctrl button.

After selecting images, click Open.

Select the gallery in which you want to upload your images. Since you can create any number of galleries,  you have to specify the name of the gallery while uploading images.

After selecting the gallery, click Upload images.

You will get a message when the uploading finishes.

Now display the gallery in a Post or Page using the code given below.

Create more galleries and display them by changing the id, i.e id=2 or id=3 etc.

Check the blog for Gallery.

You can add more galleries. For that goto Gallery-> Add Gallery/ images

Give a gallery name and click Add gallery.

While uploading images, take care of the gallery into which you want to upload.

The existing Galleries can be managed with the ‘ Gallery-> Manage gallery’ option.

Then select the gallery you want to manage.

Existing images can be renamed, deleted, sorted etc. Also you can set a preview image for the gallery.

All such options are availiable in this page.

Thats all about Galleries in WordPress.

My next post is on creating Albums.

Creating different designs in photoshop is very easy with the help of brushes. I am not talking about the ordinary brushes. There are new brushes that you can download and use  to create any pattern or design.

steps:

1. Download any photoshop brush (Download floralframe brush by clicking here.)

2. Downloaded brush is usually a zip file. If its a zip file , you will have to extract that zip file to get the brush. If you download floral frame brush from the above link, then you need’nt extract because it is ‘.abr’ file, i.e a brush. Hope you understood what i meant.

Now copy the downloaded brush ( i.e the ‘.abr’ file) and paste it to the location shown in picture below:

3. Open photoshop, select brush tool, and then do as said in pictures below…

This will open the list of brushes that are currently present. Select the one you just pasted (i.e floral frame).

You will get a message box as given below:

Click OK.

Thats all…Download more Photoshop brushes (just do a Google search on Photoshop Brushes) and have fun.
Please don’t forget to comment.

Here I’m sharing to you little theory about Fourier and a program to see how it really works.

“Joseph Fourier discovered that practically any waveform can be represented as the sum of sinusoidal waveforms.Now we think that How can waveforms with sharp corners (e.g. a triangle wave) or with discontinuities (e.g. a square wave) possibly be represented by he sum of smoothly varying sinusoids?.

Fourier theorem states that any periodic waveform can be synthesized as the sum of a fundamental sinusoid and its harmonics.
