Question

trigonometry ratios and problems on it​

Answer 1

In mathematics, the trigonometric functions are real functions which relate an angle of a right-angled triangle to ratios of two side lengths. They are widely used in all sciences that are related to geometry, such as navigation, solid mechanics, celestial mechanics, geodesy, and many others

We know the standard angles are 0°, 30°, 45°, 60° and 90°. ... Worked-out problems on trigonometric ratio of standard angle: 1. If β = 30°, prove that 3 sin β - 4 sin3 β = sin 3β.
