I need a Math EXPERT!!! Please help me in my math homework. WILL MARK AS BRAINLIST.
1 answer:
velocity is the slope (which can be calculated after finding the derivative) → given function f(x), velocity = f'(x).
acceleration is the slope of the velocity (which can be calculated after finding the derivative of the velocity) → given function f(x), acceleration is f''(x)
**************************************************************************************************
1a) A → B
f(x) =
f'(x) =
1b) B → C
f(x) =
f'(x) = = -5
1c) C → D
f(x) = 20
f'(x) = 0
Hope this helps!

First you must know that for remarkable angles: cos (0) = 1, cos (π) = - 1, cos (π / 2) = 0, cos (3π / 2) = 0, cos (2π) = 1. Then, by simple substitution in the given formula, you can find the solutions of x. Which for the interval [0, 2π) are: x = π, x = pi divided by two and x = three pi divided by two.Attached solution.
