Hi I'm having trouble visualizing why in a function such as 1/(1-x2) linear approximation of 1/(1-u) where u = x2 is the same as quadratic approximation of 1/(1-x2) The linear approximation is 1+u or 1+x2 Quadratic approximation is the same, 1+x2 Can someone explain to me why this happens...

Oh, wow thanks. It makes sense now. Thanks especially for taking the time to upload a picture.

Hi, This is also a sort of geometry question. My textbook gives a proof of the relation: sin(θ + Φ) = cosθsinΦ + sinθcosΦ. It uses a diagram to do so: http://imgur.com/gLnE2Fn sin (θ + Φ) = PQ/(OP) = (PT + RS)/(OP) = PT/(OP) + RS/(OP) = PT/(PR) * PR/(OP) + RS/(OR) * OR/(OP) = cosθsinΦ +...

Hi thanks you're right the elimination constant should be on the other side. With regards to the eliminated mass, I'm still a bit confused because the rate of elimination of the mass is dependent on the concentration of the drug in the plasma which should be the same between individuals even if...

Hi, I understand that Volume of Distribution (Vd) = elimination constant (k) * Clearance (Cl), but I can't visualize why clearance would be proportional to volume of distribution. Can someone help explain this to me? I feel like it should be a more complicated relationship. Clearance = Mass...

I think i am confusing dimensions. The axons are constant length tubes, then increasing the radius only increases the surface area in proportion to the radius, not the radius squared. The capacitance thus only increases the same as the membrane resistance and the time constant shouldn't change...

Hi and thanks for the response, Reference: http://www.kumc.edu/AMA-MSS/Study/neuro3.htm This website states that for externally stimulated neurons, larger neurons have lower threshold potentials and are thus stimulated first. Internally (Physiologically) stimulated neurons result in smaller...

Why is that large neurons have smaller threshold potentials than small neurons during external stimulation? My confusion is because the time constant should be larger, right? tau = (r_m) * (c_m). where r_m is membrane resistance and c_m is membrane capacitance Capacitance increases...

Thank you, I will try to understand this tutorial.

Hi, I'm asking this in relation to samples of DNA amplicons, but I'm so confused by probability, that I think it would be easier for me to understand in terms of simple marbles-in-bag situation. Say there is a bag of 10 different colors of marbles in equal amounts, and you are allowed to pull...
