Knowledge in 12th Mathematics
Inverse Trigonometric Functions (Theory Notes)
The inverse trigonometric functions perform the opposite operations that the sine, cosine, tangent, secant, cosecant, and cotangent perform. They are used to find the measure of an angle in a right triangle when two of the three side lengths are known.

Relations and Functions in 12th Class Mathematics
A "relation" is just a relationship between sets of information. Think of all the people in one of your classes, and think of their heights. The pairing of names and heights is a relation. In relations and functions, the pairs of names and heights are "ordered", which means one comes first and the other comes second.
Straight Lines in 12th Mathematics
A line traced by a point traveling in a constant direction; a line of zero curvature; "the shortest distance between two points is a straight line" line - a length (straight or curved) without breadth or thickness; the trace of a moving point.
Conic Sections (NCERT NOTES)
They are called conic sections, or conics, because they result from intersecting a cone with a plane as shown in Figure 1. PARABOLAS. A parabola is the set of points in a plane that are equidistant from a fixed point (called the focus) and a fixed line (called the directrix).
Mathematical Reasoning
Foundations for Mathematical Reasoning is the common starting point for all three mathematics pathways and is designed to build the mathematical skills and understanding necessary for success in a quantitative literacy, statistics, or algebra course.
