Sum of f(x) from A to Bsum f(x) from A to B
Sum of f(x) to infinitysum f(x) to infinity
π (Pi)pi
Imaginary uniti
Derivative of f(x) (embedded)f’(x)
Derivative of f(x) (just solve)derivate f(x)
Derivative of f(x,y) respect to xderivate f(x,y) in x

Indefinite integral of f(x)integrate f(x)
Integral of f(x) from a to bintegrate f(x) from a to b
Equations system between f(x) and g(x)f(x), g(x)
Area between f(x) and g(x)area between f(x),g(x)
Tangent plane to f(x,y) in the point (a,b)tangent plane f(x,y) at x=a,y=b
Solvesolve
