How to use it?
- Equation:
-
Equation x^2+9=(x+9)^2
-
Equation cos(x)=-1
-
Equation 3*x+50=77
-
Equation 5-2(x-1)=4-x
- Express {x} in terms of y where:
- 10*x+5*y=-17
- 14*x+16*y=-3
- -19*x+1*y=0
- 10*x+18*y=6
- Graphing y =:
- 2*x*log(x)+x
-
Identical expressions
- two *x*log(x)+x= zero
- 2 multiply by x multiply by logarithm of (x) plus x equally 0
- two multiply by x multiply by logarithm of (x) plus x equally zero
- 2xlog(x)+x=0
