Question

determine 2 coterminal angles one pos one neg for theta =14pi/15 .how is this solved?

Answer 1

add 2pi for positive then subtract 2pi for negative

Answer 2

so \[+ \theta = \frac{14\pi}{15} + \frac{30\pi}{15}\]
\[-\theta = \frac{14\pi}{15} - \frac{30\pi}{15}\]

Answer 3

its not suppose to be 14pi/14+2pi/1 = 16pi/15?

Answer 4

\[\frac{14\pi}{15} + \frac{2\pi}1 \ne \frac{16\pi}{15}\]

Answer 5

remember your elementary math. you have to convert fractions to common denominators

Answer 6

\[2\pi = 2\pi \times \frac{15}{15} = \frac{30\pi}{15}\]

Answer 7

ok

Answer 8

thanks
