Find, in radians the general solution of cos3x=sin5x I have said, sin5x=cos(π2−5x) so cos3x=sin5x⇒3x=2nπ±(π2−5x) When I add (π2−5x) to 2nπ I get the answer x=π16(4n+1), which the book says is correct. But when I subtract I get a different answer to the book. My working is as follows: 3x=2nπ−π2+5x 2x=π2−2nπ x=π4−nπ=π4(1−4n)
