Consider the following expression for the given conditions.

R = [(sinwD)^2/w + (coswD)^2/w] (1)

w is an integer 5 < w < 41 and R is real > 0 and 0 < D < pi/2

Assertion: 0 < R < 1

Any comment about the correctness of the assertion will be appreciated.
A numerical example will be very helpful.

What happens when w is very very large compared to 41?
