In geometry, a tangent is a line that touches the curve or a circle at a point. The point at which the tangent line and the curve meets is called... View Article
If two are perpendicular to each other, then they meet at right angles (i.e. 90 degrees) To check whether the two lines are perpendicular,... View Article
If the dot product of two vectors is calculated, the result should be a number, which is a scalar. Hence, the dot product is also called the... View Article
