When using the calculator to evaluate inverse trig functions, you really need to know about the domain and range of the function to get an accurate reading. I knew pretty much all of that except for the fact about there being 60 minutes in one degree, i think i must have missed that lesson. 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. So you have a proportion: 45/100 = ?/3600. Get a free answer to a quick problem.

Trigonometry Radian Measure and Circular Functions 65.213 65.213 To convert decimal degree to degree, minutes, and seconds, the whole units of degrees will remain the same. When using the calculator to evaluate inverse trig functions, you really need to know about the domain and range of the function to get an accurate reading. But calculators take some careful attention to details. 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. You probably know many of the trigonometry functions for the more common angles. A simpler example would be 0.5 degrees is equivalent to 0.5 * 60 = 30 minutes, so half of one degree, which makes sense.
