Problems Based on Trigonometric Ratios

The video tutorial explains the basic definitions of trigonometric ratios: sine, cosine, and tangent, using the mnemonic 'Cartur'. It further discusses the reciprocal ratios: cosecant, secant, and cotangent. The tutorial highlights that the values of these ratios remain constant for a given angle, regardless of the triangle's side lengths. It also explains that the hypotenuse, being the longest side, results in sine and cosine values always being less than one, while secant and cosecant are greater than one. The video concludes with a discussion on trigonometric notations and the concept of triangle similarity based on equal trigonometric ratios.
