CAT Important Formulae: Trigonometry & Coordinate Geometry
Trigonometry and Coordinate Geometry are two major topics in the CAT examination. This part might be a scoring section if the candidates are aware of all the formulae necessary to solve this section.
Let's take a look at all the important formulae for Trigonometry and Coordinate Geometry.
The reciprocal identities are given:
The Distance Between two Points A and B:
AB² = (Bx – Ax)² + (By – Ay)²
The midpoint of the line joining the points (x1, y1) and (x2, y2) is:
[½(x1 + x2), ½(y1 + y2)]
The equation of a line which has gradient m and which passes through the point (x1, y1) is:
y – y1 = m(x – x1)
