use the figure to find the terminal point determined by the real number t, with coordinates rounded to one decimal place. \n t = 2.3 \n (x, y) = ()
Answer
Explanation:
Step1: Recall the formula for terminal points on the unit circle
For a unit circle (x = \cos t) and (y=\sin t)
Step2: Calculate (x) - coordinate
When (t = 2.3), (x=\cos(2.3)) Using a calculator, (\cos(2.3)\approx - 0.6)
Step3: Calculate (y) - coordinate
When (t = 2.3), (y = \sin(2.3)) Using a calculator, (\sin(2.3)\approx0.8)
Answer:
((-0.6,0.8))
