In ∆ABC right angled at B, AB = 24 cm, BC = 7 cm. Determine:
(i) sin A, cos A
(ii) sin C, cos C
In given figure, find tan P - cot R.
If sin A = 3/4 , calculate cos A and tan A.
Given 15 cot A = 8, find sin A and sec A.
Given sec θ = 13/12 , calculate all other trigonometric ratios.
If ∠A and ∠B are acute angles such that cos A = cos B, then show that ∠A = ∠B.
If cot θ = 78, evaluate:
(i) (1+sinθ)(1−sinθ)/(1+cosθ)(1−cosθ)
(ii) cot²θ
If 3 cot A = 4, check whether 1−tan2A1+tan2A = cos² A - sin² A or not.
In triangle ABC, right angled at B, if tan A = 1/√3, find the value of:
(i) sin A cos C + cos A sin C
(ii) cos A cos C - sin A sin C
