For the complex expression 1+i
Calculate R = √12+12 = √2 , tan θ = 1/1 = 1, and θ=π/4 = Argument Z, where π = pi
Reiθ = √2eiπ/4, Now recognizing that the Argument can have multiple values for every complete revolution of 2π in a trigonometric circle, the argument...
This is one equation one unknown problem, and you need to slove for x
add -2x and -0.5 to both sides of the equation:
3x-2x+0.5-0.5 = 2x -2x + 5/8 - 0.5 and x = (5/8) - (1/2) = 1/8 or x = 0.625 - 0.5 = 0.125
Check solution by substituting for x in the original...
Here is another method of getting the equation of the line that pass through the point ( -9,-4) and has a slope of -5
recall that the slope m = Rise/Run = y2 -y1 / x2 - x1, and (y2-y1)= m (x2-x1)
let the point ( -9,-4) be equivalent to (...
