Question

Stormations Quick Check A student says that sin(7 + 2) = sin z. Is the student correct? If not, find the correct expression and explain why it is equivalent to sin(a + I) for any real number I. (1 point) O The student is not correct. The terminal side of the angle 1 + I lies in quadrant Il Thus, sin(n + 1) = sin c. O The student is correct The student is not correct. The terminal side of the angle + lies in quadrant III Thus, sin(1 + ) = -sin z O The student is not correct. The terminal side of the angle a + lies in quadrant IV. Thus, sin(+2) = COS T.

Answer 1

The third choice in the column.

Explanation:

Let us draw a sketch to illustrate the situation.
