3 Cos 2x 5 Sin X 1 0

3 Cos 2x 5 Sin X 1 0 - Explanation: Use the Pythagorean identity to derive a slightly different one: sin^2x+cos^2x=1 =>cos^2x=1-sin^2x Use this new identity to replace cos^2x in the actual problem, then solve it like a quadratic: 3color (red) (cos^2x)+5sinx-1=0 3 (color (red) (1-sin^2x))+5sinx-1=0 3-3sin^2x+5sinx-1=0 -3sin^2x+5sinx+2=0 3sin^2x-5sinx-2=0 Trigonometry Trigonometry is a branch of mathematics concerned with relationships between angles and ratios of lengths The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies The Greeks focused on the calculation of chords while mathematicians in India created the earliest
