COLLEGE CALCULUS. HELP!
the fundamental theorem of calculus, f(x)=∫(0,x) t^3+2t^2+2dt, and find f"(x). my answer was: f'(x)=x^3+x^2+2 f"(x)=x^4/4 + 2x^3/3 + 2x it said its wrong.
i mean i got stuck with f(pi/5)
Given f"(x)=-8sin3x and f'(0)=-1 and f(0)=-6. Find f(pi/5). i got stuck with f(pi/f) f"(x)=-8sin3x f'(x)=8cos3x+c f'(0)=8cos3(0)+c=-1 c=-9 f'(x)=8cos3x-9 f(x)=-8sin3x-9x+c f(0)=-8sin3(0)-9(0)+c=-6 c=-6 f(pi/5)-8sin3(pi/5)-9(pi/5)-6. so am i right?
Given that the graph of f(x) passes through the point (2,5) and that the slope of its tangent line at (x, f(x))is 3x+5, what is f(3) ?

I'm trying to find the intersection point of y=x-2 and y=sqrt(x). I tried letting both equations equal each other but kept coming up with the points (4,1) and (1,4) however these aren't right as the answer should be (4,2) but I am unable to get this answer. Help please?
