🔥 Square Root & Argument of Complex Numbers | NDA Maths | By Dheeraj sir | Mission Selection This video from MISSION SELECTION focuses on two crucial topics in Complex Numbers for NDA and other defence exams: Square Root of a Complex Number and Argument & Principal Argument of a Complex Number (0:07). The instructor emphasizes the importance of comprehensive study (0:45) including thorough concept understanding, regular revision (2:35), and taking mock tests (1:42) to improve speed and accuracy. The video covers the basics of complex numbers, including their representation (4:59), identifying real and imaginary parts (5:10), and different forms like Cartesian, Polar, and Euler's form (6:10). Key concepts discussed include: Modulus of a Complex Number (8:17): Defined as the distance of the complex number from the origin on the Argand plane (8:51). Formulas and quick methods using Pythagorean triplets are explained (14:36). Argument of a Complex Number (12:47): This is the angle made by the line connecting the complex number to the origin with the positive x-axis. The formula for the first quadrant is introduced (13:59). Conjugate of a Complex Number (20:59): Involves changing the sign of the imaginary part, and a property relating the product of a complex number and its conjugate to the square of its modulus is derived (23:09). Multiplicative Inverse (26:09): A method for quickly calculating the inverse using the conjugate and the square of the modulus is shown (26:29). Identifying the Quadrant (28:08): Explains how to determine which quadrant a complex number lies in based on the signs of its real and imaginary parts (28:45). Square Root of a Complex Number (33:36): Detailed formulas and examples are provided for finding the square root, including specific cases for sum and difference (33:36, 38:00). Special Property of Complex Numbers with Modulus 1 (43:55): Demonstrates that if the modulus of a complex number is 1, its inverse is equal to its conjugate, leading to a useful simplification in expressions (44:22). The video is designed to help aspirants develop a strong conceptual understanding and effective problem-solving strategies for competitive exams. इस वीडियो में Mission Selection YouTube Channel पर हम Complex Numbers के दो सबसे महत्वपूर्ण टॉपिक्स— 👉 Square Root of a Complex Number 👉 Argument & Principal Argument of a Complex Number को concept + exam approach के साथ विस्तार से समझेंगे। इस वीडियो में आप जानेंगे 👇 ✅ Complex number का square root निकालने की complete method ✅ Argument और Principal Argument में अंतर ✅ Complex plane में quadrant का सही use ✅ NDA, SSC और Defence exams में पूछे जाने वाले questions की तैयारी 📌 यह वीडियो खास तौर पर तैयार किया गया है: NDA | Airforce | Navy | Defence Exams के aspirants के लिए। 🎯 Mission Selection का उद्देश्य है — “Concept Clear + Selection Sure” वीडियो पसंद आए तो 👍 Like करें 🔁 Share करें 🔔 Mission Selection चैनल को Subscribe जरूर करें #MissionSelection #ComplexNumbers #SquareRootOfComplexNumber #ArgumentOfComplexNumber #PrincipalArgument #NDA_Maths #DefenceExams #MathsByDheerajSir #CompetitiveMaths #PolarForm
