PHYSICS
The phase constant φ is the value of |ωt| at the point where x has its maximum value, for ω*t between -2 pi and 0. The value of (ωt + φ) will be zero there; the cos function will have its maximum value.

Calculus (Urgent Help)
Not only that, but you are wrong on number 6. A minimum value of f'(x) at x = c does NOT imply an extreme value, although the reverse is certainly true if the sign changes from - to +. f''(x) could be undefined at f'(c) which would make it a critical value of f'(x) since it is...
