    Finding constant in a function

    Hi can you explain the l'hospital's rule? I'm sorry I'm just starting Calculus and my teacher assigned this problem and we have yet to learn it. Thanks.

    Finding constant in a function

    Determine all values of the constant a such that the following function is continuous for all real numbers. f(x) = ax/tan x, if x≥ 0 a^2 -2, if x<0 I've tried to plug in zero but the tan x throws me off because plugging in zero will give me a 0/0. Other than that I am stuck on what to do.

    Solving for Pressure in Four Cylinder Thermodynamic Problem

    yeah I was considering that. And to find the volume in state 4, I would have to use PV=nRT correct ? since T isn't constant ?

    Solving for Pressure in Four Cylinder Thermodynamic Problem

    Ok my answer to the volume are wrong, do I use P1V1=P2V2 or do I use PV=nRT equation ?

    Solving for Pressure in Four Cylinder Thermodynamic Problem

    Thanks ! i have managed to solve a and b but now i am stuck on c I believe the answer to c is isobaric, because P=F/A is not affected by the growing volume nor the temperature. and it can't be isothermal because the temperature is changing. and I don't quite understand how adiabatic works.
