Ex 5.5,6 (Method 1)Differentiate the functions in, (π₯+1/π₯)^π₯+ π₯^((1+1/π₯) ) Let π¦= (π₯+1/π₯)^π₯+ π₯^((1 + 1/π₯) ) Let π’ = (π₯+1/π₯)^π₯ , π£ = π₯^((1 + 1/π₯) ) π¦ = π’+π£ Differentiating both sides π€.π.π‘.π₯. ππ¦/ππ₯ = (π (π’ + π£))/ππ₯ ππ¦/ππ₯ = ππ’/ππ₯ + ππ£/ππ₯ Now ππ£/ππ₯ = ππ’/ππ₯ + ππ£/ππ₯ Putting values of ππ’/ππ₯ & ππ£/ππ₯ π π/π π = (π+π/π)^π ((π^π β π)/(π^π+ π)+π₯π¨π β‘(π+ π/π) ) + π^((π + π/π) ) ((π + π β πππβ‘π )/π^π )
