I have a study sheet and 2 practice problems I can't answer, but DON'T SOLVE THEM I want to know what to review to solve them myself. My question is, what topics in calculus cover these concepts so I can study it? I'm predicting anti-derivatives but I'm not entirely sure.
1. If f'(x) = sqrt(x)(4+4x), f(1)=10, find f
2. If g''(t) = 3/(sqrt(t)), g(4) = 20, g'(4) = 7, find g
Thanks :)

I already had the answer key but thanks again for the explanation anyway ~_~

Question - 1:
i) You are given f '(x); and you need to find f(x) for the given conditions.
ii) Given f '(x) = 4{(x)^(1/2)} + 4{(x)^(3/2)}
iii) Now integrate this and you will get f(x) = Integral of f '(x) + C
iv) Use the given conditions, at x = 1, f(x) = 10; solve this you will get the value of C
Substitute this value of C in the f(x) equation in step (3) ==> You have your end answer.
Question - 2:
i) First integrate g"(t); Let this be A. You get g'(t) = A + c
ii) Using the given conditions, t = 4 and g'(4) = 7, evaluate for the value of c
iii) Plug this value of c, you get g'(t).
iv) Then, integrate g'(t) obtained in (iii) above. Let this be B; So you get g(t) = B + k
v) As previous, using the given conditions, g(4) = 20, evaluate for k
arctan(u), arcsin(u), arccos(u) and so on. all turn a trignometric ratio into an perspective value arctan(a million) as an occasion is 40 5 tiers or (pi/4) arcsin(.5) is 30 tiers a) ought to be superb for all arctan values when you consider that they bypass from minus to plus infinity
