Find the exact values of the six trigonometric functions of the given angle. If any are not defined, say "not defined." Do not use a calculator.
In Problems convert each angle in radians to degrees.
Nautical Miles A nautical mile equals the length of arc subtended by a central angle of 1 minute on a great circleโ on the surface of Earth. See the figure. If the radius of Earth is taken as 3960 miles, express 1 nautical mile in terms of ordinary, or statute, miles.
For a circle of radius r, a central angle of u degrees subtends an arc whose length s is . Discuss whether this is a true or false statement. Give reasons to defend your position.
If the radius of a circle is and the length of the arc subtended by a central angle is also , then the measure of the angle is .
