Question 2 (a) part Q2. (a) . From the figure (i) given below, find the values of : (i) sin B (ii) cos C (iii) sin B + sin C (iv) sin B cos C + sin C cos B. (b) From the figure (2) given below, find the values of: (i) tan x (ii) cos y (iii) cosec2 y – cot2 y (iv) 5 sin x + 3 sin y - 3 c o t y .

Assuming AB=6 cmand, BC=10 cmand, AC2+AB2=BC2or, AC=BC2-AB2 =102-62 =100-36 =64 =8 cm(i) sin B=ACBC =810=45(ii) cos C=ACBC =810=45(iii)sin B + sin C=ACBC+ABBC=AC+ABBC=8+610=1410=75(iv) sinBcosC+sinCcos B=ACBC×ACBC+ABBC×ABBC=AC2+AB2BC2=(8)2+(6)2(10)2=100100=1 0 View Full Answer Ahmad answered this what's the difficult to evaluate basic trigonometric ratios? 0
