Calculus Fundamentals:
Power Rule: d/dx[x^n]=n*x^(n-1). Product Rule: d/dx[f*g]=f'g+fg'.
Chain Rule: d/dx[f(g(x))]=f'(g(x))*g'(x). Quotient Rule: d/dx[f/g]=(f'g-fg')/g^2.
d/dx[sin(x)]=cos(x), d/dx[cos(x)]=-sin(x), d/dx[e^x]=e^x, d/dx[ln(x)]=1/x.
integral(x^n dx)=x^(n+1)/(n+1)+C, integral(e^x dx)=e^x+C.
Fundamental Theorem: integral[a to b]f(x)dx=F(b)-F(a) where F'(x)=f(x).
