Math, Still Need Help!
a) - yes the sum of ax+b and cx+d is still linear b) - no the product of ax+b with cx+d produces a term in x^2. Quadratics are not one-to-one c) - yes multiplying a linear like ax+b by a constants keeps it linear.

Calculus - Still Need Help! Anyone!
a. Find the derivative, set to zero dx/dt= -e^-t * sint+ e^-tcost=0 tanT=1 check that. t= PI/4 or 3PI/4 Now which will make it to the left (negative x)? b. d^2x/dt^2= d/dx e^-t(cost-sint) take that dervative. Then, put in the equation given ax" + x'+ x=0 and solve for A

Calculus (Optimization, Still Need Help)
I just wanted to correct something for my equation, it should be: V = (14 - 2x)(8 - 3x)(x), which simplifies to V = 112x - 44x^2 - 4x^3. Take the derivative: V' = 112 - 88x - 12x^2 Now all I need are the roots, any help? I think I found one around 1.10594, possibly?
