Question

How can one determine θ from sin(θ) = 0.4? A) Use the inverse sine function

B) Use the cosine function
C) Use the tangent function
D) Use the inverse cosine function

Answer 1

To determine θ from sin(θ) = 0.4, you can use the inverse sine function or arcsine function.

Step-by-step explanation:

To determine θ from sin(θ) = 0.4, you can use the inverse sine function or arcsine function. The inverse sine function is denoted as sin-1 or asin.

Using the inverse sine function, you can plug in the value 0.4 to find the angle θ. The inverse sine of 0.4 is approximately 23.58 degrees or 0.4115 radians.

Therefore, option A) Use the inverse sine function is the correct answer.
