Function Commands
Cosine of x cos(x)
Sine of x sin(x)
Tangent of x tg(x)
Natural logarithm of x ln(x)
Base-b logarithm of x log(b,x)
Multiplication *
Division /
k-power of x x ^ k
Square root of x sqrt ( x )
k-th root of x di x x ^ (1/k)
Absolute value of x abs(x)
Limit (automatic) of f(x) Lim f(x)
Limit of f(x) for x that goes to k Lim f(x) x to k
Limit of a sequence lim f(n)
Infinity infinity
Infinity (negative) -(infinity)
Sum of f(x) from A to B sum f(x) from A to B
Sum of f(x) to infinity sum f(x) to infinity
π (Pi) pi
Imaginary unit i
Derivative of f(x) (embedded) f’(x)
Derivative of f(x) (just solve) derivate f(x)
Derivative of f(x,y) respect to x derivate f(x,y) in x
Derivative of f(x) in the point x=a derivate f(x), x=a
Indefinite integral of f(x) integrate f(x)
Integral of f(x) from a to b integrate 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
Solve solve
