STUDENT WORKSHEET OF CIRCLE (LKPD LINGKARAN)

I am back with hot stuff today.

When I was on my lecturing for Workshop Math 2. We have to make a student worksheet about circle area.

There are two versions, English and Indonesian.

Here the screen shoot for English version.

Microsoft Math 2007

This software is called Microsoft Math 2007.
It really useful for you to study about mathematics. For example, if you are confused how to graph a mathematics function, this software will help to get the graphic of a function.

You can download this math software here.

Happy mathematics. Thanks. Gomawo ^_^

SETS (Himpunan)

Sets is a material of Senior High School grade VII semester2. I had made this material some month ago, now I want to share it for everyone if you need to know about this material.

I convert it become pdf. I can't write it here directly because some of this writing consist of math equation.

Here, some previews:

SETS

I.  UNDERSTANDING SETS

A set is a collection of objects which can be clearly defined.

Example:

-  A group of the color of traffic light.

-  A herd of reptile animals.

-  A group of humans who born in October.

Look at the following groups which are not considered as a set:

-  A group of handsome boys in my class 

-  A group of cheap cloths in the market.

II.  SYMBOL AND MEMBERSHIP OF A SET

A set is usually denoted by a  capital letter  such as A, B, C, …, Z. The objects 

which are included in a set may be expressed using brackets.

Example:

1.  A set of natural numbers which are less than 5.

K = {1,2,3,4} 

2.  A set of basic color.

G = {red, yellow, green}
