Inequation:
0,5^x>0,5
4x^2+16<0
5x-2>3
4+12x>0
Integral of d{x}:
x/(x^2+2)
Graphing y =:
x/(x^2+2)
Derivative of:
x/(x^2+2)
Identical expressions
x/(x^ two + two)<(two *x)^- one
x divide by (x squared plus 2) less than (2 multiply by x) to the power of minus 1
x divide by (x to the power of two plus two) less than (two multiply by x) to the power of minus one
x/(x2+2)<(2*x)-1
x/x2+2<2*x-1
x/(x²+2)<(2*x)^-1
x/(x to the power of 2+2)<(2*x) to the power of -1
x/(x^2+2)<(2x)^-1
x/(x2+2)<(2x)-1
x/x2+2<2x-1
x/x^2+2<2x^-1
x divide by (x^2+2)<(2*x)^-1
Similar expressions
x/(x^2+2)<(2*x)^+1
