2 Hour To Become An Expert In Solution Of Triangle As we know, for some triangle problems, current method involve solutions that require the use of 2 rule or require the use of one rule twice that involve many steps. As example, when we are given 2 sides and a non-included angle, to find the third side, the method now involves users of the rule of the sine and later the user of the rule of the cosine. For another example, to find a non-included angle when given two sides and an included angle, one of the methods now involves using cosine rule. Therefore, the purpose of this book is to train to train anyone, especially a math teacher teachers to solve all triangle problems simple, just use one rule and only once. According to Albert Einstein If you can't explain it simply, you don't understand it well enough. On the other hand, If you can solve all triangle problems simply, you can be said to be an expert in Solution Of Triangle . The 2-hour To Become An Expert In Solution Of Triangle workshop for 24 teachers in Seberang Prai Tengah successfully trained all teachers how to solve all triangle problems simple, just use one rule and only once. Before the workshop, all 24 teachers agreed that they did not know how to solve all triangle problems simple, just use one rule and only once. But after the workshop, all 24 teachers agreed that they knew how to solve all triangle problems simple, just use one rule and only once. The objective of this book is the same as that of the workshop, to train anyone, especially a math teacher, become an expert in Solution Of Triangle in two hours. Worksheets of Peter Chew rule and method are also provided to enhance the reader's understanding of these two new simple knowledge. Step-by-step answers to the worksheet are also provided for reference.
