MATH 1200 Lecture Notes - Lecture 5: Sinusoidal Model, Arc Length, Central Angle
Document Summary
To convert from 37. 425 degrees to dms, multiply 0. 425 degrees by 60 minutes/ 1 degree. The result is 25. 5 minutes, or 25 minutes and 30 seconds. With bearing, when only one angle is given the bearing is measured in a clockwise direction from due north. Distance of one minute of longitude at the equator ( or arc with (1/60) degree and the earth"s radius at the equator) unit circle coterminal angles. Evaluating trig functions of a nonquadrantal angle z. Draw the angle z in standard position, being careful to place the terminal side in the correct quadrant. Label a point p on the terminal side of the angle. Draw a perpendicular segment from p to the x-axis. If this triangle is one of the triangles whose ratios you know, label the side accordingly. If it is not, then you will need to use your calculator.
