To ask Unlimited Maths doubts download Doubtnut from - https://goo.gl/9WZjCW `cos3x-sin2x=0.` The solutions to our equation are x = πk and x = (π/2) + πk, where k is any integer. To solve this equation, we will use the following rules and properties:. h→0. ( sin x(cos h − 1) h. + cos x sin h h. ) ( use lim h→0 cos h − 1 h. = 0 and lim h→0 sin h h. = 1. ) = sin x · 0 + cos x · 1. = cos x ! We have found that ... Apr 4, 2025 ... Explanation: Given cot2x. cot3x = 1 ⇒ cos2x. cos3x – sin2x.sin3x= 0 ⇒ cos(2x+3x) = cos5x = 0 0 < x < π. Feb 12, 2024 ... The question is as Follows:- Sin(2x) + Cos(3x) = 0, 0. ...
