The following are all angle measures (in radians, rounded to the nearest hundredth) whose sine is 0.98 . Which is the principal value of arcsin(0.98)? Choose 1 answer: (A) -11.20 (B) -4.91 (C) 1.37 (D) 7.65

Find Principal Value: We need to find the principal value of arcsin(0.98), which is the inverse sine function value that lies in the range of -π/2 to π/2 radians.Use Calculator or Table: To find the principal value, we use a calculator or a table to find the arcsin(0.98). The arcsin function will return the angle in radians whose sine is 0.98.Calculate arcsin(0.98): Using a calculator, we find that arcsin(0.98) is approximately 1.37 radians. This value is within the range of -π/2 to π/2 radians, so it is the principal value.Check Options: We check the given options to see which one matches our calculated value. The correct option is (C) 1.37.

Find Principal Value: We need to find the principal value of $\arcsin(0.98)$ , which is the inverse sine function value that lies in the range of $-\frac{\pi}{2}$ to $\frac{\pi}{2}$ radians.
Use Calculator or Table: To find the principal value, we use a calculator or a table to find the $\arcsin(0.98)$ . The $\arcsin$ function will return the angle in radians whose sine is $0.98$ .
Calculate $\arcsin(0.98)$ : Using a calculator, we find that $\arcsin(0.98)$ is approximately $1.37$ radians. This value is within the range of $-\frac{\pi}{2}$ to $\frac{\pi}{2}$ radians, so it is the principal value.
Check Options: We check the given options to see which one matches our calculated value. The correct option is (C) $1.37$ .
