Each degree is divided into 60 minutes, and each minute further divided into 60 seconds. In the mid-1500s, the mathematician Franois Vite created tables of all six functions correct to the nearest minute. This doesnt even scratch the surface. 0% average accuracy. Please submit your feedback or enquiries via our Feedback page. So, to express an angle measuring 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. In the mid-1500s, the mathematician Franois Vite created tables of all six functions correct to the nearest minute. Multiply the decimal by 60 60. The whole number becomes the minutes. Multiply 0.023 0.023 by 60 60. Take the remaining decimal and multiply by 60 60 and take the whole number portion to find the seconds. Multiply 0.38 0.38 by 60 60.

This doesnt even scratch the surface. thanks for the help, i know what to do now. Divide that by 60 to get the number of minutes: 1620/60 = 27 minutes, with no remainder (i.e., no seconds). To find an inverse sine, cosine, or tangent, use the buttons available on the calculator. Not familiar with the minute measure in trigonometry? The calculator will only tell you what you ask, not necessarily what you need to know.

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

Since one degree has 60 min, we can write that x = 0.6358 * 60 So x is 38.148 min. 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). WebMathematics is definitely among the top fears of students across the globe. Calculators have made life so much easier. The 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.
