Popular Examples

f(x)=(x^2-x-12)/(x+6)

f (x) = \frac{x ^{2} - x - 12}{x + 6}

y = \frac{2 x - 5}{x - 3}

f(x)=x^2-12x+100

f (x) = x^{2} - 12 x + 100

y=(2-sqrt(x^{1/4)})/(4-x^{1/4)}

y = \frac{2 - x ^{\frac{1}{4}}}{4 - x ^{\frac{1}{4}}}

f(x)=(sin(x)+tan(x))/(cot(x)+csc(x))

f (x) = \frac{sin ( x ) + tan ( x )}{cot ( x ) + csc ( x )}
