What are the trigonometric ratios for the right-angled triangle ABC, with angle A as the reference angle?
The trigonometric ratios for angle A in triangle ABC are: sin A = AB/AC, cos A = BC/AC, and tan A = AB/BC
In the right-angled triangle ABC, right-angled at B, if the hypotenuse AC = 5cm, base BC = 3cm, and perpendicular AB = 4cm, what are the values of tan θ, sin θ, and cos θ?
tan θ = AB/BC = 4/3, sin θ = AB/AC = 4/5, and cos θ = BC/AC = 3/5
What is the etymology of the word 'trigonometry'?
The word 'trigonometry' is derived from the Greek words 'tri' (meaning three), 'gon' (meaning sides), and 'metron' (meaning measure).
What are the various trigonometric ratios for specific angles used in trigonometry?
The various trigonometric ratios for specific angles include sine, cosine, tangent, cosecant, secant, and cotangent.
What are the three sides of a right-angled triangle and how are they related to the trigonometric ratios?
In a right-angled triangle, the three sides are the hypotenuse, opposite, and adjacent sides, which are related to the trigonometric ratios as sine (opposite/hypotenuse), cosine (adjacent/hypotenuse), and tangent (opposite/adjacent).
