` f(x)=sum_(n=0)^oo(f^((n))(a))/(n!)(x-a)^n `
Matrices and column vectors are simple to type
Grouping brackets don't have to match
piecewise defined function are based on matrix notation
Complex subscripts are bracketed, displayed under lim
` int (x+1)(e^(x//2) - 1) dx = (x+1)(2e^(x//2) - x)- int (2e^(x//2)-x) dx `
` \ \ \ \ =(x+1)(2e^(x//2) - x) - (4e^(x//2) - x^2/2) + C `
` \ \ \ \ = 2xe^(x//2) -x^2 + 2e^(x//2) -x - 4e^(x//2) + x^2/2 + C `
` \ \ \ \ = 2e^(x//2)(x-1)-x-x^2/2 + C `
