What is tangentially?

Tangentially refers to something that is done or exists in a way that is only slightly related or connected to something else. It can also refer to something that is done or moving in a direction that is perpendicular or at an angle to something else. In mathematics, tangentially refers to a line or curve that touches another line or curve at a single point without crossing it. In communication or conversation, tangentially can refer to going off-topic or making a connection that is not directly related to the main discussion.
