WebExpress 3 cos θ + 4 sin θ in the form R cos (θ – α), where R and α are constants, R > 0 and 0 < α < 90°. To find the value of R, use Pythagoras's Theorem using the coeffecients of cos θ and sin θ. The correct answer should be R=5. Expand the expression R cos (θ – α). Equate the expanded expression with 3 cos θ + 4 sin θ to find the value of θ.

Web10 nov. 2024 · Question 2: If tan a = 4/5 find cos a and sin a? Solution: In right angled triangle We have tan a = 3/4 Therefore Tangent θ = Perpendicular / Base = AB / BC AB = 3 BC = 4 Therefore as per the Pythagoras theorem We have AC 2 = BC 2 + AB 2 AC 2 = 4 2 + 3 2 AC 2 = 16+ 9 AC 2 = 25 AC = 5 So now we have AB = 3 AC = 5 BC = 4 Now to … Web23 aug. 2024 · Trigonometry is the study of the relationship between the sides and angles of triangles.
