Actually, trig function values have been around for centuries. Not familiar with the minute measure in trigonometry? 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. Where did all these function values come from? The Hi guys, i have a maths worksheet that is due in tomorrow and i cant remember how to do some of the questions. Calculators have made life so much easier. You can find tables that give function values to the nearest degree and the nearest minute. So the decimal form (0.45) you have above needs be converted into minutes and seconds (the 172 degrees will stay the same.). To calculate the sine, cosine or tangent of an angle, press the , or key and then type in the size of the angle. Every degree can be divided into 60 minutes, and each of those minutes can be divided into 60 seconds. This top-and-bottom arrangement saves space in a book.
\nBefore handheld calculators, the trig tables found in textbooks or mathematical table publications were the only way to go for the layman. Question 298392: Find, to the nearest minute, the angle whose measure is 3.45 radians. To double check, you can say is 27/60 equal to 0.45? Do you trust your calculations? Minutes and seconds are used to express fractions of degrees. One degree is equal to 60 minutes and one minute is equal to 60 seconds. So, to express an angle measuring (seven degrees, 30 minutes, 30 seconds). Many cultures and mathematicians dabbled in creating tables of values for the trig functions. The first detail, of course, is to have working batteries available. Matt H. Question 298392: Find, to the nearest minute, the angle whose measure is 3.45 radians. But calculators take some careful attention to details. Founded in 2005, Math Help Forum is dedicated to free math help and math discussions, and our math community welcomes students, teachers, educators, professors, mathematicians, engineers, and scientists. Jon P. round to the nearest hundredth. You need only two given values in the case of: one side and one angle two sides area and one side Remember that if you know two angles, it's not enough to find the sides of the triangle. Dummies helps everyone be more knowledgeable and confident in applying what they know. 16.12 (/11) 4.6 ft. Embedded content, if any, are copyrights of their respective owners. Answer. 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). Find the values of for the following (Give your answers in degrees and minutes): tan -1 2.53 = 68 25 59.69 ( The symbol denotes seconds. 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. The missing number works out to be 1620 seconds. 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.
