Sin of More Than 2pi, 360 DegreesDate: 8/6/96 at 21:27:11 From: Anonymous Subject: Sin of More Than 2pi, 360 Degrees Hello, How do you find the sin of 2020? Date: 8/6/96 at 21:40:13 From: Doctor Robert Subject: Re: Sin of More Than 2pi, 360 Degrees Do you mean 2020 degress or 2020 radians? Since the sine function repeats itself every 360 degrees, you can subtract any multiple of 360 from 2020 and take the sine of that angle. In other words, sin 2020 = sin 1660 sin 1300 = sin 220 degrees. sin 220 = -sin 40 = -0.6428. If you're dealing with radians, subtract multiples of 2pi from 2020. Make sure that your calculator is in radian mode. Your answer should be .0441. -Doctor Robert, The Math Forum Check out our web site! http://mathforum.org/dr.math/ |
