Question 2 Differentiate sin β‘(cos β‘(π₯2)) with respect to π₯ .Let π¦ = " " sin β‘(cos β‘π₯2) We need to find derivative of π¦ π€.π.π‘.π₯ i.e. π¦^β² = (π ππβ‘γ (cosβ‘γπ₯^2 γ )γ ) ππ¦/ππ₯ = π(π ππβ‘γ (cosβ‘γπ₯^2 γ )γ )/ππ₯ = cos (cosβ‘γπ₯^2 γ ) . π(cosβ‘γπ₯^2 γ )/ππ₯ = cos (cosβ‘γπ₯^2 γ ). (βsinβ‘γπ₯^2 γ ) . π(π₯^2 )/ππ₯ = cos (cosβ‘γπ₯^2 γ ). (βsinβ‘γπ₯^2 γ ) . 2π₯ = β 2x sin π^π. cos (cos π^π)
