Trigonometry (Part 1/3) JEE Main PYQ + Theory | Prabhat Ranjan

Trigonometry Question 1-10 (Part 1/3) Class 11, 12 Mathematics Boards, JEE Main, JEE Advanced, IIT JEE Full course from basic JEE Main Question Practice JEE Main PYQ + Theory by Prabhat Ranjan for class 12, boards, IIT JEE 2025, JEE Main 2025, JEE Advanced 2025, IIT JEE 2026, JEE Main 2026, JEE Advanced 2026.

"Trigonometry (Part 1/3) JEE Main PYQ + Theory" by Prabhat Ranjan is the first part of an in-depth exploration into trigonometry, tailored for students preparing for Class 11 and 12 Mathematics boards, as well as competitive exams like JEE Main, JEE Advanced, IIT JEE 2025, and 2026. In this session, covering questions 1-10, students are guided through the essential trigonometry topics, with a focus on solving previous year questions (PYQs) from JEE Main. The video integrates foundational theory with practical problem-solving techniques, making it a valuable resource for mastering trigonometry concepts such as trigonometric identities, formulas, and shortcuts, crucial for scoring high in both board exams and entrance tests.

All these aspects have been covered by Prabhat Ranjan in full detail in his new YouTube video.

I am Prabhat Ranjan, currently pursuing B.Tech in Mechanical Engineering from NIT Jamshedpur.

Timeline:
00:00 Introduction
01:42 1) For any θ € (pi/4 , pi/2) , the expression 3(sinθ - cosθ)4+ 6 (sinθ + cosθ)2 + 4 sin6θ equals
07:41 2) the value of cos(pi)/(2^(2))x cos(pi)/(2^(3))....cos(pi)/(2^(10))x sin(pi)/(2^(10)) is
13:43 3) If α = cos − 1 ( 3/5 ) , β = tan − 1 ( 1/3 ) , where 0 less than α , β less than π 2 , then α − β is equal to
19:26 4) The equation y = sinx sin(x + 2) - sin2(x+ 1) represents a straight line lying in : [JEE-Main 12-04-2019-S-1] (1) Third and fourth quadrants only (2) First, third and fourth quadrants (3) First, second and fourth quadrants (4) Second and third quadrants only
26:36 5) Let a and ß be two real roots of the equation (k +1) tan2 x -2 . A tanx = (1-k), where k (not equal to - 1) and 2 are real numbers. If tan2(a + ß) = 50, then a value of A is
31:37 6) if l=sin2(π16)−sin2(π8) and m=cos2(π16)−sin2(π8) then
35:29 7) If 0 less than x, y less than pi and cosx + cosy - cos(x + y) = 3/2, then sinx + cosy is equal to
45:51 8) The value of cot pi/24 is : [JEE-MAIN_25-07-2021_S2]
53:07 9) If tan ( π/ 9 ) ,x, tan ( (7 π)/ 18 ) are in arithmetic progression and tan ( π/ 9 ) , y, tan (( 5 π)/ 18 ) are also in arithmetic progression, then |x – 2y| is equal to
58:25 10) Let alpha=max x€R {8^2sin3x.4^4cos3x} and beta= min x€R {8^2sin3x.4^4cos3x} .If 8x^2+bx+c=0 is a quadratic equation whose roots are a1/5 and ß1/5, then the value of c - b is equal to
