The seond derivative is zero if . WHY?
I have done part a and b, but need help with part c.A) show that satisfies the equation
b)the expression can be written as where R and α are positive constants,
0 < α < pi/2. Find the values of R and α, correct to 3 decimal places.
(c) What is the smallest positive value of x where y has a point of inflection?
Thank you.
Okay thanks, I am not quite sure why this result would make the second derivative zero?
I know how to find the coordinates of a stationary point, but don't get what the question is asking, is it asking me to find all the points of inflection on the curve
and than find the lowest value of x corresponding to a point of inflection?
thank you for clarifying.
