To ask Unlimited Maths doubts download Doubtnut from - https://goo.gl/9WZjCW `cos3x-sin2x=0 It is indeed true that \sin^{2}(x)=1-\cos^{2}(x) and that \sin^{2}(x)=\frac{1-\cos(2x)}{2}. Notice that cos 2 ( x ) : = ( cos ( x ) ) 2 is not the same thing as cos ( 2 x ) . It is indeed true that sin 2 ( x ) = 1 − cos 2 ( x ) and that sin 2 ( x ) = 2 1 − c o s ( 2 x ) . Solve, for 0 < x < 2pi Sin(2x) = Cos(2x) Which I whittled down to Cos(x) - Sin(x) = 2 Now I'm stuck.
