this is just a general question, one that keeps coming up everytime i take a test or quiz.
I understand that the derivative of a constant is zero, but I don't understand when you use that zero to multiply or divide in a problem, and when you just ignore that zero.
For example x^2/3...
I am graphing a parabola for a calculus problem. I understand how you factor and use the two x values as your x-intercepts, but I'm not sure how this one would be graphed.
y=4x^2 - 25. I understand how the vertex of the parabola would be at negative 25, but I have no clue what to do woith...
Determine the value of c so that f(x) is continuous on the entire real line if
f(x)={ x^2, x<_3 (less than or equal to)
{ c/x, x>3
I've been trying by just guess and check, but I have absolutely NO idea!
Please help!
I have a summer calc assignment due tomorrow, and I've been stuck on these two problems. Help is appreciated!
Solve for y:
x^2 + y^2 + 4x - 6y +12=0
I tried this:
x^2 + 4x + 12 = -y(y-6)
But I don't think that was correct. THe left side wont' factor, and I don't htink that is the right...
oh yes thanks!
how about this one.
I'm not sure how to simplify it down, and how to distribute the ^2 once it has been plugged in.
x^2 + y^2 +3x=0 when x=rcostheta and y=rsintheta
I'm taking Calculus next year and over the summer I have some assignments.
This one is due in a couple of hours, so any help would be appreciated!
If cos2t=1/3 and *0<_ 2t <_ pie, find cost. t=theta *less than or equal to
I don't know how to use the identities to help me...
