are you a detective? LOOL. I need the derivative because from it I can get the slope of the normal at any point since I want to find the equation of multiple normal lines at different points to draw "the hair" of the thing I am drawing. No more questions please with this sort

this is not a homework, i am trying to use a mathematical software to draw images using mathematical equations :) Can you please tell me a way to not "keep it simple" since i need the values of a and b since I can't draw it that small!

Homework Statement Hello I have this circle with the equation : [/B] (x-a)^2+(y-b)^2=r^2 I want to find dy/dx for it 2. Homework Equations (x-a)^2+(y-b)^2=r^2 The Attempt at a Solution I am looking on the internet and it appears that I should use what is called "Implicit differentiation"...

There is obviously going to be no difference. a change in a third decimal place will not affect the data right?

ok. I will do this tomorrow

why plot terminal velocity? can't i just plot the coefficients of dynamic viscosity since i am studying the relation between temp. and viscosity!

I just did what you suggested. I found the terminal speed for every temperature value. I assumed that the density is constant with the value of 1.41 g/cm^3. I assumed that the radius of the marble is 1.5cm and that it is made from steel with density 8.05g/cm^3. and g=980cm/s^2. After that I...

I will do this idea now. I will inform you of the results.

My supervisor said that I can assume it is constant but I should explain that well. What do you suggest I do?

Ok, I will try to do that, thanks

ok thanks again

That is what I thought too. I will use the same type of honey/from same company. I will measure the density at room temperature and use it throughout, right?

thank you so much for answering my concerns. I have to ask my supervisor for this, I think I will end up using a constant value but then write about it in the "Sources of error" section and how I should have used the true density values in the "Improvements" section. Thank you again legend! If I...

does what I said make any sense?

The fluid I will use is Honey, here is its table (http://www.viscopedia.com/viscosity-tables/substances/flower-honey-blended/) I don't want to calculate the density or use the accurate values because i need to have one independent/dependent variable while others should be controlled...
