The terminal point P(x, y) determined by a real number t is given. Find sin(t), cos(t), and tan(t).

Question

The terminal point P(x, y) determined by a real number t is given. Find sin(t), cos(t), and tan(t).

(-1/4, 4√3/7)

sin(t)=

cos(t)=

tan(t)=

Answer 1

r² = (-1/4)² + (4√3/7)²

sin t = (4√3/7) / r

cos t = (-1/4) / r

tan t = (4√3/7) / (-1/4)
