Can anyone give me some tricky , or conceptual questions on "tangents and normals" which i can use to teach my fellow students in a lecture tomorrow .I am equipped with ordinary questions(like finding equation of tangent and normal when function is given) but i want the students to use their brains..do help please :)

Best ResponseYou've already chosen the best response.1@moha_10 i need a questions above ordinary level which are tricky and need use of "brain" on the topic "tangents and normals".As i told "I am equipped with ordinary questions(like finding equation of tangent and normal when function is given)"

Best ResponseYou've already chosen the best response.1do we usually define the normal as pointing out from the curve or in ? are there two normals to a flat line?

Best ResponseYou've already chosen the best response.1u see there are a few students who just byheart the formula and appy it mechanically .. i want to teach them why using brain is important

Best ResponseYou've already chosen the best response.1nt formula i mean mechanical proces like finding f'(x) then using slope point form get to eqn of tangent and normal

Best ResponseYou've already chosen the best response.2maybe u can give a equation of a circle and ask them to find the equation of tangent passing through (a,b) where (a,b) is either center or inner point of a circle...they would not be able to find slope only.........

Best ResponseYou've already chosen the best response.1@mukushla I think if y=ax^2+ax+1 x=2ay+1 will be workable, changed the y^2 to y

Best ResponseYou've already chosen the best response.0Try: Find the shortest distance between two curves f1(x) and f2(x). Example: f1(x)=x^2, and f2(x)=2(x1)^2+4

Best ResponseYou've already chosen the best response.1where do we bring in tangents in that?

mathmate

Best ResponseYou've already chosen the best response.0This is not an easy problem, because the tangents have to be parallel, but at different values of x on each curve. They would minimize the distance after that.
