- Equation:
-
Equation 9-4x=3x-40
-
Equation x+4=0
-
Equation x^2+6x+9=0
-
Equation (x-2)^5+(4-x)^5=2
- Express {x} in terms of y where:
- 18*x+12*y=18
- -20*x-13*y=15
- 12*x-3*y=-2
- 17*x+1*y=-11
- Graphing y =:
- sin(x)+cos(x)
- Canonical form:
- sin(x)+cos(x)
- Integral of d{x}:
-
sin(x)+cos(x)
-
Identical expressions
- sin(x)+cos(x)= one
- sinus of (x) plus co sinus of e of (x) equally 1
- sinus of (x) plus co sinus of e of (x) equally one
- sinx+cosx=1
-
Similar expressions
- 1+tan(x)+tan(x)^(2)+tan(x)^(3)=sinx+cosx/cos^3x
- sinx+cosx=1/sqrt(2)
