whereat Then just make the proper substitutions to prove it.
Thanks for replying, but could you please elaborate further..
You're expected to know that is the second derivative, whereas the first is then by just knowing this you can compute Once you get and put them together into the equation and the rest is algebra.
d2y/dx2 = (1-x^2)^-3/2...? I can't sub in dy/dx and d2y/dx2 and make it equal 0
whereat Dinner is served.
OH man. I completely ignored the x in 2x. n00b error. Thank you for your help.
Hello, Erghhh! It seems straight-forward enough. Exactly where is your difficulty? Given that: . , show that: . We have: . And: . Then: . . . . . . . . . .
Thanks, i see what i'm doing now. i just made a stupid error.
