Like.
There appears to be a simple formula for the radius of the inscribed circle of any right triangle that goes as the area of the triangle... -
SammyS replied to the thread I Geometry problem of interest with a 3-4-5 triangle.Not only is this true for all right triangles, it's true for all triangles in general.

Can you please specify where in @haruspex's statement, is what your instructor said that he needs and what that is?

In geometry, there are only three ways of determining that two lines are parallel: definition, postulate, and proof. Diagrams are not to...

SammyS reacted to A.T.'s post in the thread B The work done by two objects on each other with
Agree.
Avoiding confusion by being less explicit about what you mean? Is this a joke? -
Just because we survived some bad teachers, doesn't mean we have to propagate bad teaching.

SammyS reacted to Steve4Physics's post in the thread Intersection of a circle and a sine curve with Agree.
I'll give it a go... What is the maximum number of times (##N## ) a circle* can intersect the graph of ##y=\sin x##? a)##N \le 2## b)...

SammyS replied to the thread Geometry: Similar Shapes.What is "SF" ? I suppose may be Scale Factor ? The given figure may be fooling you into assuming more than what is stated.

SammyS reacted to PeroK's post in the thread Limit of piecewise function using epsilon delta with Like.
That's not really how we are supposed to construct a proof here. Instead, for ##0<\epsilon <1##, we should let: $$\delta =...

SammyS reacted to PeroK's post in the thread Limit of piecewise function using epsilon delta with Agree.
In general, for a right hand limit at ##a## you are looking for:$$a < x <a +\delta$$And not $$0<|x-a|< \delta$$PS I see this was in the...
