- Equation:
-
Equation x^2+9x+20=0
- Equation 9^x-26*3^x-27=0
-
Equation 3x²-27=0
-
Equation sin5x-sqrt(3)cos5x=0
- Express {x} in terms of y where:
- 4*x-16*y=6
- 10*x-1*y=10
- sqrt(x^2+y^2+4x-6y-12)+(x^2+10x-27)=8-|y-9|+|y-3|
- 15*x-17*y=19
- Derivative of:
-
tan(x-pi/4)
- Graphing y =:
-
tan(x-pi/4)
-
Identical expressions
- tan(x-pi/ four)=(- one)/sqrt(three)
- tangent of (x minus Pi divide by 4) equally ( minus 1) divide by square root of (3)
- tangent of (x minus Pi divide by four) equally ( minus one) divide by square root of (three)
- tan(x-pi/4)=(-1)/√(3)
- tanx-pi/4=-1/sqrt3
- tan(x-pi divide by 4)=(-1) divide by sqrt(3)
-
Similar expressions
- tan(x+pi/4)=(-1)/sqrt(3)
- tan(x)=-1/(sqrt(3))
- tan(x-pi/4)=(1)/sqrt(3)
- cot(x-pi/12)-1/sqrt(3)=0
- cot(x+pi/6)=-1/sqrt(3)
-
What you mean?
- tan((x - pi)/4) = -1/(sqrt(3))
- tan(x - pi/4) = -1/(sqrt(3))
- tan(x - pi/4) = -1/(sqrt(3))
You entered:
