Henrik the meerkat, the friend of gottfried and bernhardt, says that if an angle in radians is larger than 2pi, then the sine of the angle is larger than 1 . bernhard disagrees, and says that no matter what the radian measure of an angle is, the sine of that angle is always between -1 and 1. who is correct and why?and

When angles are restricted to real numbers, Bernhard is correct. The sine function has a range of -1 to 1 (inclusive).

When angles are allowed to be complex numbers, the magnitude of the sine of an angle may exceed 1. In this realm, both Henrik and Bernhard are incorrect.

The sine function, defined for all x, is always between -1 and +1. It begins at (0,0), increases to 1 at x = pi/2, decreases to -1 at x = 3pi/2, and increases to 0 as x reaches pi. Thus, the range is [-1,1], regardless of the value of x. Bernie is correct. Gottfried got fried.

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.
