Question

For the following angles find a conterminal that is located in the interval 0 < 0 < 27 A. A = -2 B.0=1 C.0 = 197 3 4 6

Answer 1

The coterminal angles in the given range is;

For angle

`-(2\pi)/(3)\text{ the coterminal is -}(2\pi)/(3)+2\pi=(-2\pi+6\pi)/(3)=(4\pi)/(3)`
`\text{The coterminal of }(11\pi)/(4)\text{ is }(11\pi)/(4)-2\pi=(11\pi-8\pi)/(4)=(3\pi)/(4)`
`\text{The coterminal of }(19\pi)/(6)\text{ is }(19\pi)/(6)-2\pi=(19\pi-12\pi)/(6)=(7\pi)/(6)`
