A must series for those seriously looking for a strong foundation for their trig learning. It begins with the Pythagorean Theorem and the primary trig ratios sine, cosine and tangent and finding unknown sides and angles in right triangles and then progresses to solving word problems involving the primary trig ratios. The series covers the reciprocal trig ratios (secant, cosecant, cotangent) and exact value special angles.

Lessons Included
Below are the descriptions for each of the lessons included in the series:

Trig: Basic Trigonometry Part I, Sin, Cos, Tan 300
This 77 minute trigonometry lesson is for the beginning trigonometry student or is a good refresher for anyone who has not recently studied trigonometry. The lesson reviews triangles, the Pythagorean theorem and the 3 primary trig ratios (Sine, Cosine and Tangent. In this lesson you will be introduced to the concepts of trigonometry and learn how to:
 name the parts of a triangle and recognize acute, obtuse and right angle triangles; isosceles, equilateral and scalene triangles; and similar triangles
 use the Pythagorean Theorem, hypotenuse, opposite side and adjacent side soh cah toa or sohcahtoa
 find the sin, cos and tan of any angle,
 use your calculator for trigonometry
 find the length of the sides in any right angle triangle
 find the unknown angle in any right angle triangle
 solve right trianglesThis lesson contains explanations of the concepts and 27 example questions with step by step solutions plus 6 interactive review questions with solutions.
Lessons that will help you with the fundamentals of this lesson include:
 135 Solving Linear Equations Part I (http://www.mindbites.com/lesson/5068)
 160 Operations with Radicals (http://www.mindbites.com/lesson/5065) 
Trig: Word Problems  Sine, Cosine & Tangent 305
This 78 minute trigonometry lesson is an opportunity to see how the skills learned in Lesson 300 Basic Trigonometry Part I are used to solving word problems using the 3 primary trig ratios, sin, cos and tan. You find unknown sides and angles in right angle triangles to solve word problems that involve:
 a kite on the end of a string, diagonal of a rectangle, support wires, shadows, ladders, trees, buildings, stairways and more
 angle of elevation and angle of depression
 rise & run
Sample problem: An airplane is flying over a forest at an altitude of 1600 ft. when the pilot sights a fire. He measures the angle of depression and finds it to be 46 degrees. How far is the fire, to the nearest tenth of a ft. from a point on land directly below the airplane?This lesson contains explanations of the concepts and 17 example questions with step by step solutions plus 3 interactive review questions with solutions.
The following lesson will help you with the fundamentals of this lesson:
 300 Basic Trigonometry Part I (http://www.mindbites.com/lesson/5125) 
Trig: Basic Trig Part II Sec, Csc & Cot 315
This 67 minute trigonometry lesson follows Lesson 300 Basic Trigonometry Part I to study the 3 reciprocal trig ratios, cosecant (csc), secant (sec) and cotangent (cot) or ctn. Special angles and exact value are also covered. This lesson will show you how to:
 find the reciprocal ratios of an acute angle
 use your calculator with cosecant, secant and cotangent
 use cosecant, secant and cotangent to solve problems
 work with special angles (30, 45 & 60 degrees) and exact values (values obtained without the use of a calculator)This lesson contains explanations of the concepts and 15 example questions with step by step solutions plus 4 interactive review questions with solutions.

Clear & precise, brought into clarity & understanding what i could not gain from the Text book! Well done!
The actual word problems were kind of silly dealing with kites and whatnot but the math was solid and bringing it all together from the problem was helpful.
The teacher person has a monotone voice but following along with or without sound is actually very easy. So if you need trig practice I found it helpful.
