This is single valued and equals the constant

#### Explanation:

If u = arc sin x and v = arc cos x, u + v is many valued and is of the

form of an odd multiple of

u + v is single valued and equals the constant

range is specified as #[alpha, alpha+pi/2], and in this case, the

derivative is 0. Here,

Otherwise, it is not differentiable.
