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 :)

@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)"

Hi @AravindG you can use the study material of some coaching centres of IIT they have many such questions

do we usually define the normal as pointing out from the curve or in ? are there two normals to a flat line?

u 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

hartnnBest ResponseYou've already chosen the best response.2
maybe 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.........

@mukushla I think if y=ax^2+ax+1 x=2ay+1 will be workable, changed the y^2 to y

Try: Find the shortest distance between two curves f1(x) and f2(x). Example: f1(x)=x^2, and f2(x)=2(x1)^2+4

where do we bring in tangents in that?
 one year ago

mathmateBest ResponseYou've already chosen the best response.0
This 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.
