Question

____The radian measure of an angle equals the length of the arc it intercepts on the unit circle. ___ Any degree measure can be converted to radians by multiplying the number by 180/pi. ___ To construct the inverse of a trigonometric function, the function must be restricted to a domain on which the function is either always increasing or always decreasing. ____ The length of an arc intercepted by an angle is proportional to the radius; therefore, a central angle of pi/5 in a circle with radius k will intercept an arc with length k pi/5. ____ A triangle with side lengths 7, 11, and 14 has an area of 120 Squareroot 21.
