What's the derivative of 1+u2 ?Rosebud said:
The derivative of 1+u^2 with respect to u is 2u du.SammyS said:
Do you know the method of substitution ?Rosebud said:
No.SammyS said:
That should have been a BIG hint.Rosebud said:
Thanks for the tip. I did that but I still fail to see the connection. Can you, or someone else, give me the next step?SammyS said:
Numerator? There is no fraction here unless you you consider 1 as the denominator.DeldotB said:
ahh, thought I saw a / in front of the root.Rosebud said:
That helped immensely. Thank you so much. I forgot that I could use substitution more than once.Rosebud said:
SammyS said:
So, you do know substitution.Rosebud said:
Rosebud said:
Yes, I know substitution. You asked me if I knew the method of substitution, which I understood as, you asking if I knew which method of substitution that I should use.SammyS said:
