I am trying to do test corrections . I have attached a copy of the test. I don't need help with all I just need help with 1a,b,c,d and 3a,b,c. That is all for now
you really insist huh?
1a.. i believe you know ..
so the first thing you do is to set
1b.. you may want to divide first and you will get a constant + 1 over something.. that 1 over something is an form when integrated..
EDIT: I didn't see that there was a power of 7. anyways, use a substitution on the denominator with out the power..
1d.. you may want to separate first.. for the first addends, set .. for the second addends, it just a direct application of what you should have learned..
here (under a different name, no less). I would advise others (though the moderators have the final say) not to provide direct solutions to or work for these problems, but to instead offer general help or guidance.
if you were able to read all content of the attached file, you will see that all of his solutions were, in fact, given at the last pages before s/he even asked us to help him/her.
and it will be up to us now whether we will continue to give the complete solution (which in this case, no we should not)
(Also, regarding your carefully-gender-neutral language, I think the name on the test removes the ambiguity )
