Question

4. If y = sinh [m log (x + (x2 +1) }], show that (x^2 + 1)d²y/dx^2+x*dy/dx= m^2y​

Answer 1

Answer:

y = log [x + √ x 2 + 1 x2+1], Differentiating with respect to x, we get Differentiating again with respect to x, we get Read more on Sarthaks.com - https://www.sarthaks.com/1051135/if-y-log-x-x-2-1-then-prove-that-x-2-1-d-2y-dx-2-x-dy-dx-0?show=1051138#a1051138
