Mathematics Formulas
Mathematics Key Formulas:
1. Trigonometry:
sin + cos = 1, tan = sin/cos
2. Differentiation:
d/dx (x^n) = nx^(n-1)
d/dx (sinx) = cosx, d/dx (cosx) = -sinx
3. Integration:
x^n dx = x^(n+1)/(n+1) + C
1/x dx = ln|x| + C
4. Definite Integration:
f(x) dx = F(b) - F(a)
5. Vectors & 3D:
Dot product: AB = |A||B|cos
Cross product: AB = |A||B|sin
6. Matrices:
A = adj(A)/|A|, |AB| = |A||B|
7. Probability:
P(E) = favorable outcomes / total outcomes
