Mathematics Classroom Activity Class 11 Mathematics Topic: Trigonometric ratios of Quadrantal angles Objective: How trigonometric function values are determined for a Quadrantal angles Materials Required: Graph sheet Compass Protractor Ruler Pencil Step-by-Step Activity: 1. Draw the Unit Circle: Take a graph sheet and mark the x-axis (cosine axis) and y-axis (sine axis) . Draw a unit circle (radius = 1 unit) centered at the origin (0,0). 2. Identify Quadrantal Angles: Quadrantal angles lie along the axes: 0° (or 360°) → Positive x-axis 90° → Positive y-axis 180° → Negative x-axis 270° → Negative y-axis 3. Plot the Points on the Unit Circle: For each quadrantal angle, the terminal side lies on the x-axis or y-axis. The coordinates of the point where the angle intersects the unit circle are: 0° (360°) → (1, 0) 90° → ...
Visualizing Consistency in Systems of Linear Equations Using GeoGebra 📊 Description: In this tutorial, we explore how to determine the consistency of a system of linear equations using GeoGebra’s dynamic graphing tools. You’ll learn how to visualize: ✅ Unique solutions (consistent & independent) ✅ Infinitely many solutions (consistent & dependent) ✅ No solution (inconsistent system) We’ll analyze different cases with 2D and 3D graphs, helping you understand the geometric interpretation of linear systems. Whether you're a student or an educator, this visualization will enhance your understanding of linear algebra concepts. 🔹 Topics Covered: ✔️ Graphing linear equations in GeoGebra ✔️ Identifying intersecting, parallel, and coincident lines/planes ✔️ Using the RREF (Reduced Row Echelon Form) tool for consistency checks ✔️ Real-world examples for better intuition
