I'm so confused with inflection and horizontal inflection
are they the same thing?
what is the best way to see if there is a horizontal inflection. by using the first derivative,with the test of turning points
or the second derivative, with the test for concavity?
please help with these questions.
show working out please! :)
1. Find the point of intersection of the normals to the parabola x^2 =-12y at the points (4, -1 1/3) and (-2, -1/3)
2. a. Find the equation of the tangent to the parabola x^2 =12y at the point P (6,3). ( the answer is x-y-3=0...
Find the value of n for which the equation (n+2)x^2 +3x-5=0 has one root triple the other
can you please show the working out for the whole question
i tried doing it before but it didn't work out
thanks
would someone very lovely answer this questions for me and show the working out?
find the exact value of f''(2) if f'(x) = x times by the square root of (3x-4)
muchly appreciated! please and thankyou :)
