Hi, I am an 11th grade student beginning to look into some college options. I am interested in pursuing a career in proctology and have been reading some preliminary books on the topic. Can anyone recommend a college or pre-med program that would offer a strong proctology prog...
Critical Points, Etc.
find the values for a, b, and c such that the function f(x)= x^3 + ax^2 + bx+ c has a critical point at (1,5) and an inflection point at (2,3). a= -6 b= 3 c= 7 i got those, but they're wrong. i'm not sure why. :/
Tangent Lines (2)-Calculus
find an equation of the line tangent to y= sqrt(25-x^2) at the point (3,4) i got y= x/8 + 29/8 this is wrong. but im not sure why. can you explain thank you
Tangent Lines-Calculus
a line is tangent to the curve y= (x^2 + 3)/ (x+3)^1/2 at the point where x=1. write the equation of this line i get y= 3x-1 yet it's wrong. please explain thank you
