Math mini-contest problem for Day 2 on D.Buzz for May 2021 😎

A calculator of Ahmad can perform only the sine function in trigonometry. The arc tangent value of an angle is 30.26Β°. What is the sine value of the angle?

Sort: Β 
arctan(x) = 30.26 deg = 0.5281 rad
x = tan(0.5281) = 0.5834
sin(x) = sin(0.5834) = 0.5509
