Q. One degree is equal to 60 minutes and one minute is equal to 60 seconds. problem and check your answer with the step-by-step explanations. Divide that by 60 to get the number of minutes: 1620/60 = 27 minutes, with no remainder (i.e., no seconds). Each degree is split up into 60 parts, each part being 1/60 of a degree. In the mid-1500s, the mathematician Franois Vite created tables of all six functions correct to the nearest minute. You can find tables that give function values to the nearest degree and the nearest minute. Each minute is split up into 60 parts, each part being Again, what about that 47-degree angle? Trigonometric Functions. Copyright 2005-2022 Math Help Forum. Calculators have made life so much easier. One degree is equal to 60 minutes and one minute is equal to 60 seconds. Calculators have made life so much easier. 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 Thats three values for three different angles in three different functions. The question reads: Find the size of the angle , correct to the nearest minute, in cach of the following. WebFind the exact length of the arc intercepted by the given central angle in the figure to the right Translations of the Graphs of Sin & Cos Determine the period of the given function y = -5 cos (x/2 + /3) The Unit Circle Definitions The figure shows an angle is standard position with its terminal side intersecting the unit circle. Thats fine and dandy when you have a 30-60-90 right triangle or a 45-45-90 right triangle. WebMathematics is definitely among the top fears of students across the globe. Answer. This doesnt even scratch the surface. The missing number works out to be 1620 seconds. 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. Some favorites are:

Question 298392: Find, to the nearest minute, the angle whose measure is 3.45 radians. This doesnt even scratch the surface. Q. Again, what about that 47-degree angle? All rights reserved. For the exercises 46-49, use the given information to find the area of the sector. Do you trust your calculations?
\nActually, trig function values have been around for centuries. answered 03/17/15. 1) find reference angle (always acute) 2) find the trig function value for the angle (remember special angles) 3) determine the sign 2. 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? Can they be computed by hand?
\nGoing back to the basics of trigonometry, you find a great deal of information from a right triangle. Round your final answer to the nearest tenth as needed. Thats three values for three different angles in three different functions. Mathematics is concerned with numbers, data, quantity, structure, space, models, and change. There are 60 minutes in a degree, so .45 degree is .45*60 = 27 minutes.

Answer. Get the values for sine, cosine, tangent, cosecant, cotangent, this indicates that i have to use the Tangent function. 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. 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. Choose the correct ratio. WebYou can put this solution on YOUR website! Find the values of for the following (Give your answers in degrees and minutes): a) tan = 2.53 b) sin = 0.456 c) cos = 0.6647 Solution: a) Press tan -1 2.53 = 68 25 59.69 ( The symbol Are there different formulas to use to find these values?
