*minute*measure in trigonometry? For the exercises 46-49, use the given information to find the area of the sector. This top-and-bottom arrangement saves space in a book.\n

Before handheld calculators, the trig tables found in textbooks or mathematical table publications were the only way to go for the layman. If you very carefully construct a right triangle with an angle of 47 degrees, you may be able to get some fairly accurate measurements of the sides and see that this 47-43-90 right triangle has sides measuring about 0.7314-0.6820-1 (or some multiple thereof). Are there different formulas to use to find these values? WebUsing Right Triangle Trigonometry to Solve Applied Problems. Many of the tables have three functions at the head of each column and the respective co-functions of the three functions at the bottom of the same columns. The next detail is to have the calculator set in the correct mode degrees or radians depending on what your application is and what form the angles that youre using are in. When you want the secant of an offbeat angle, such as 47 degrees, you need to resort to some resource such as a table of values or a scientific calculator.

\nWhere did all these function values come from? problem and check your answer with the step-by-step explanations. So, to express an angle measuring. If you know the measure of an acute angle in a right triangle and you have the measures of the sides, then you can compute the function values with some careful dividing. Note that the , and keys automatically open a bracket for you. Question 298392: Find, to the nearest minute, the angle whose measure is 3.45 radians. The calculator will only tell you what you ask, not necessarily what you need to know.

\nWhichever method you use, just be sure to carefully follow any directions and have a working knowledge of the relationships between the different functions.
