# (d y) / (d x) = 4/3 * x ^ (- 2/3) + 8/3 * x ^ (1/3)
# (d ^ 2) / (dt ^ 2) = 8/9 * x ^ (- 2/3)
Explicaţie:
# Y = 4x ^ (1/3) + 2x ^ (4/3) #
# (dy) / (dx) = 1/3 * 4 * x ^ ((1 / 3-1)) + 4/3 * 2x ^
# (d y) / (d x) = 4/3 * x ^ (- 2/3) + 8/3 * x ^ (1/3)
# (d ^ 2y) / (dt ^ 2) = - 2/3 * 4/3 * x ^ ((2/3-1) 3-1)) #
# (d ^ 2y) / (dt ^ 2) = - 8/9 * x ^ ((- 5/3)
# (d ^ 2) / (dt ^ 2) = 8/9 * x ^ (- 2/3)
