Popular Examples

f(x)=((t^2-t+1))/((t^2+1))

f (x) = \frac{( t ^{2} - t + 1 )}{( t ^{2} + 1 )}

f(t)=e^{5t}sin(t)

f (t) = e^{5 t} sin (t)

f(g)=3g^2-16g+15

f (g) = 3 g^{2} - 16 g + 15

f(x)=-sqrt(2-x^2)

f (x) = - 2 - x^{2}

f(x)=7sin(x)+7cos(x),0<= x<= 2pi

f (x) = 7 sin (x) + 7 cos (x), 0 \leq x \leq 2 π
