2) Discuss. Using a calculator to solve a certain problem, you need to find the sine of 4 rad. Your study partner uses his calculator and tells you that sin4=0.0697564737. On your calculator, you get sin 4 = - 0.7568024953 What has happened? Who is correct and what mistake was made by the other person.

can someone help please

**Problem Discussion:** Using a calculator to solve a problem, you need to find the sine of 4 radians. Your study partner uses his calculator and tells you that sin(4) = 0.0697564737. On your calculator, you get sin(4) = -0.7568024953. **Task:** What has happened? Who is correct, and what mistake was made by the other person? --- **Analysis:** The discrepancy lies in the mode of calculation: degrees vs. radians. - **Your Calculation (sin(4) = -0.7568024953):** - Likely done in radians, which is correct for 4 radians. - **Partner's Calculation (sin(4) = 0.0697564737):** - Likely done in degrees, leading to an incorrect result for a radian measure. **Conclusion:** You are correct. Your partner mistakenly used degrees instead of radians to perform the calculation.
