Ex 5.3, 1 Find ππ¦/ππ₯ in, 2π₯ + 3π¦ = sinβ‘π₯ Given 2π₯+3π¦ = sinβ‘π₯ Differentiating both sides π€.π.π‘.π₯ (π (2π₯ + 3π¦))/(ππ₯ ) = (π(sinβ‘γπ₯)γ)/(ππ₯ ) (π(2π₯))/(ππ₯ ) +(π(3π¦))/(ππ₯ )=(π(sinβ‘γπ₯)γ)/(ππ₯ ) 2 (π(π₯))/(ππ₯ ) +"3" (π(π¦))/(ππ₯ )=(π(sinβ‘γπ₯)γ)/(ππ₯ ) 2 + 3 ππ¦/(ππ₯ ) = πππβ‘π 3 ππ¦/(ππ₯ ) = cosβ‘π₯ β 2 π π/(π π ) = π/π (πππβ‘π β 2)
