Answer:
Step-by-step explanation:
Question. 1 : In ∆ ABC, right-angled at B, AB = 24 cm, BC = 7 cm. Determine:
(i) sin A, cos A
(ii) sin C, cos C
Question 2: If Sin A = 3/4, Calculate cos A and tan A.
Question.3: If ∠A and ∠B are acute angles such that cos A = cos B, then show that ∠ A = ∠ B.
Question 4: If 3 cot A = 4, check whether (1-tan2A)/(1+tan2A) = cos2 A – sin2 A or not.
Question 5: In triangle PQR, right-angled at Q, PR + QR = 25 cm and PQ = 5 cm. Determine the values of sin P, cos P and tan P.
Question 6 :SinA+Sin2A=1, then find the value of (cos2A+cos4A).
