Web2 jul. 2016 · Acos∅ -bsin∅ = x and asin∅+bcos∅ = y on squaring both the equations x² = a²cos²∅ + b²sin²∅ - 2abcos∅sin∅ y² = a²sin²∅ + b²cos²∅ + 2abcos∅sin∅ on adding x² + y² … WebStep 1:Simplify the function using trigonometric identities. As we know that sin θ + α = a and sin θ + β = b. Here, we will apply the trigonometric function cos on both sides. The equation will become. Step 2: Apply the trigonometric identity cos ( A - B) = cos ( A) cos ( B) + sin ( A) sin ( B) on the right hand side. WebSolution The correct option is C - ( b / a 2) s e c 3 θ Explanation for the correct option. Step 1: Differentiate x and y w.r.t θ x = a sin θ ⇒ d x d θ = a cos θ y = b cos θ ⇒ d y d θ = - b sin θ Step 2: Find d y d x and d 2 y d x 2 d y d x = d y d θ × d θ d x = - b sin θ a cos θ = - … surface scratches on dining room table
