If sin theta 4/5 then find cos theta
Web24 mei 2024 · Simplify cos4theta - sin4theta 2. If (cos θ + sin θ) = √2 cos θ, Show that (cos θ - sin θ) = √2 sin θ 3. Prove that 1/ (sin θ + cos θ) + 1/ (sin θ - cos θ) = 2 sin θ/ (1 – 2 cos2 θ) 4. If tan A = (sin θ - cos θ)/ (sin θ + cos θ) then prove that sin θ + … WebSolution The correct option is B ± 3 Step 1. Finding the value of 5 s i n θ - 3 c o s θ: Given, 3 sin θ + 5 cos θ = 5... ( i) Let 5 sin θ – 3 cos θ = p... ( i i) Step 2. Squaring and adding (i) and (ii), we get 9 sin 2 θ + 25 cos 2 θ + 30 sin θ cos θ + 25 sin 2 θ + 9 cos 2 θ – 30 sin θ cos θ = 25 + p 2
