comment optimization with non smooth constraint
@JesseRJ MATLAB is not a good solver. Maybe CVXOPT? abel.ee.ucla.edu/cvxopt/examples/index.html There are others that are free. The best paid one is CPLEX sold by IBM

comment optimization with non smooth constraint
@JesseRJ Modern optimizers have a special type for that constraint.

comment optimization with non smooth constraint
@JesseRJ are you using linear optimization only, or can you have binary variables?

Likely, etaps means stages and eagle means tail.

Do you know derivatives? can you use L'Hospital's rule?

comment Find $\lim_{x \to -8} \frac{\sqrt{1 - x} - 3 }{ 2 + \sqrt[3] {x}}$
PLease exhibit your work on the problem and we will be glad to give some hints. How about expanding the root in the numerator into Taylor series around $x=1$?

comment What am I doing wrong? (using the formula for lowering powers)
@Cherry_Developer Because $\cos(4x)$ is one object, and also $-\cos(4x) \neq cos(-4x)$
