How Do You Find Sin 40 Without A Calculator? [Solved]
How to Find the Value of Sin 40 Degrees? The value of sin 40 degrees can be calculated by constructing an angle of 40° with the x-axis, and then finding the coordinates of the corresponding point (0.766, 0.6428) on the unit circle. The value of sin 40° is equal to the y-coordinate (0.6428). ∴ sin 40° = 0.6428.
