Question

This problem is intended to clear up any confusion on how to enter answers for some of the problems in this assignment. Recall there is difference between giving EXACT answers and APPROXIMATE answers. One important fact to keep in mind as you enter exact answers in radians which involve the number pi, type pi in order to enter the exact value of pi. WeBWorK reads pi as a number just as it does any other number. So for instance 2pi can be entered as 2*pi, 2(pi), 2pi, pi+pi, ect. When you want to approximate pi on your calculator, on TI model calculators hit 2nd and the A Key to get the value for pi. Consider the following question: Determine the radian measure of the angle 60degree : Enter the exact angle in radians: Enter an approximation for the radian measusre to three decimal places: Since the exact radian measure is (60. Pi/180 ) = pi/3 in the first box above you need to type pi/3, where pi is understood to be the number pi. In the second box, you are asked to approximate the number pi/3 to three decimal places, so you should enter 1.047

Explanation / Answer

60 degree in radians is pi/3

for approximate value

pi/3=22/7*3=22/21 = 1.047619.....=1.048
