Single and double anti-derivatives

 

Try an f(x):   anti-derivative

 

The parser understands the following functions f(a):

abs(a)    sin(a)    cos(a)     tan(a)    ln(a)    log(a)     int(a)    frac(a)
asin(a)    acos(a)    atan(a)    sinh(a)     cosh(a)    tanh(a)    asinh (a)    
acosh(a)    atanh(a)    ceil(a)    floor(a)     round(a)    exp(a)    sqr(a)    
sqrt(a)     sign(a)    step(a)     random(a)
