Due to the way trig ratios are defined for non-acute angles, the value of a trig ratio could be positive or negative, or even 0.There are many identities that are based on trigonometric functions.So I'll give you a few seconds to think about what the measure of angle W is.

Solving these problems will help the student to acquire professional skill necessary for a teacher who must know how to solve mathematical problems of the high-school level.
This book is not only a collection of problems, it is rather a study aid for practical work, as can be seen in the structure of the text book.
This study aid is intended for students of physical and mathematical faculties of pedagogical institutes.
The book contains about 2000 examples, problems, and exercises of which 1700 problems are for solving independently. Identical Transformations of Rational Functions 11 Sec. Identical Transformations of Irrational Functions 20 Sec. Identical Transformations of Exponential and Logarithmic Functions 29 Sec.
Yes, the sine, on the first period, takes on the value of I've done the algebra; that is, I've done the factoring and then I've solved each of the two factor-related equations. So now I can do the trig; namely, solving those two resulting trigonometric equations, using what I've memorized about the cosine wave.
From the first equation, I get: However (and this is important!
So I'll give you a few seconds to think about how to figure out what a is. So if we're looking at angle Y, relative to angle Y, this is the opposite. Well if we don't remember, we can go back to Soh Cah Toa. And I will get, if I round to the nearest tenth like they ask me to, I get 10.7. So we can divide both sides by that, by cosine of 65 degrees.
These cancel out, and we are left with, if we flip the equal around, we're left with a is equal to 5 times the tangent of 65 degrees. So we now know that this has length 10.7, approximately. So we could use trigonometric functions that deal with adjacent over hypotenuse or opposite over hypotenuse. Well we see from Soh Cah Toa cosine deals with adjacent over hypotenuse.
Along with rather simple problems, there are also problems whose solution requires serious and sometimes inventive work.
In the course of preparing the manuscript for print we tried to distribute the space among the basic types of “school” problems in algebra and trigonometry.
