The sign function is used to represent the absolute value of a number when used in trigonometry. It is also referred to as the signum function in math.

ADDING: same sign, add and keep that sign. opposite sides, subtract their absolute values and use the sign of the number with the larger absolute value SUBRTRACTING: change the sign of the subtrahend (2nd number) then ADD using rules above.

You can use the Pythagorean identity to solve this:(sin theta) squared + (cos theta) squared = 1.

ax2 + bx + c = 0 , find the value of x . b2-4ac>o x is real (2 different values will solve) b2-4ac=o -> a double root (a single real number will solve it) x=real numbers. b2-4ac<0 x= two complex number roots (either pure imaginary or a complex number with real and imaginary components)

What's your question? To solve an absolute value inequality, knowledge of absolute values and solving inequalities are necessary. Absolute value inequalities can have one or two variables.

write two numbers that have the given absolute value. 1.4

Absolute Value means the distance from 0, and so you should solve the equation with the number inside the Absolute Value lines as a positive and then solve again as a negative.

To solve it by coordinate graphs you would take a point from the line and plug in the X and Y value into the equations and or inequalities.

An absolute value may not need a number line to solve. Absolute value means the distance form zero regardless of the sign.

Fractions make no difference to absolute values.

To solve equations with absolute values in them, square the absolute value and then take the square root. This works because the square of a negative number is positive, and the square root of that square is the abosolute value of the original number.

o wow your asking me do do this well i can so i will show you. [x]+5=11 you will first subtract 5 from 11 and 5 so it would look like this---[x]=6 so the answer would be 6 or -6 because any number in a absolute value sybol is always positive.
