Functions of a Real Variable, chapter IV, § 1. EXISTENCE THEOREMS

For the scalar equation x′=sin⁡txx' = \sin tx one has I=H=RI = H = \mathbf{R} and the right-hand side is bounded on I×HI \times H, so (IV, p. 173, cor. 1) every integral is defined on all of R\mathbf{R}.

Bourbaki puts the proof directly after the statement, so what is above is the statement and its proof together.
