i would like to understand how gravity works and how to find forces please draw and teach me them
ahadahadixui
so gravity pulls up right
ahadahadixui
so it points to the right
ahadahadixui
could you teach me how to take derivatives using first principle and draw graphs for an example
ahadahadixui
so it is like intergals right
ahadahadixui
how to do intergals

y

Forces on an Incline
W = mg
N
f
θ
W = mg
F_parallel = mg sin(θ)
a = g sin(θ)

Gravity on an Incline
W = mg
N
F_g = mg (downwards)
W = mg

Derivative from First Principles
f(x)
x
x + h
f(x+h) − f(x)
f′(x) = lim(h→0) [f(x+h) − f(x)] / h
slope = Δy / Δx = [f(x+h) − f(x)] / h
Tutor
∫ f(x) dx = F(x) + C
Area = lim(n→∞) Σ f(xᵢ) Δx

d/dx (2 + x²) ≠ 0
d/dx (2) = 0
d/dx (x²) = 2x
