How to use it?
- Equation:
-
Equation x^4-5x^2+4=0
-
Equation (x^2-9)^2+(x^2-2*x-15)^2=0
-
Equation 5x-25+2x^2=17+13x
-
Equation (x-4)(x^2+16x+64)=13(x+8)
- Express {x} in terms of y where:
- 4*x+13*y=13
- 17*x-19*y=1
- -1*x+19*y=-10
- 10*x+9*y=-4
-
Identical expressions
- tg(x-(pi/ four))=-(sqrt three)/3
- tg(x minus ( Pi divide by 4)) equally minus ( square root of 3) divide by 3
- tg(x minus ( Pi divide by four)) equally minus ( square root of three) divide by 3
- tg(x-(pi/4))=-(√3)/3
- tgx-pi/4=-sqrt3/3
- tg(x-(pi divide by 4))=-(sqrt3) divide by 3
