A. sinalpha =square (Simplify your answer, including any radicals. Use integers or fractions for any numbers in the expression ) B. sinalpha is undefined.

To find the exact values of the trigonometric functions, we first need to determine the angle whose terminal side contains the point . We can do this by finding the reference angle and then using the appropriate quadrant.Step 1: Find the reference angle.The reference angle is the acute angle formed between the terminal side of the angle and the x-axis. Since the point is in the third quadrant, we can use the Pythagorean theorem to find the reference angle.Let and . Then, .The reference angle is .Step 2: Determine the angle .Since the point is in the third quadrant, the angle is .Step 3: Find the trigonometric functions.Using the angle , we can find the trigonometric functions as follows: Therefore, the correct choice is A. .
