    Hello, ^_^Engineer_Adam^_^!

    Find the rectangular form of: . x .= .3Ětan▓θ . . y .= .2Ěsec▓θ

    . . - - - . . .x
    We have: .-- .= .tan▓θ . [1]
    . . - - - . . .3

    . . - - - . . y
    . . . . . . . -- .= .sec▓θ . [2]
    . . - - - . . 2

    . . . . . . . . . . . . . . . . .y . .x
    Subtract [1] from [2]: . -- - -- .= .sec▓θ - tan▓θ .= .1
    . . . . . . . . . . . . . . . . .2 . .3


    We have the line: .y .= .(2/3)x + 2


    But be careful!

    Since tan▓θ > 0, then x > 0

    Since sec▓θ > 1, then y > 2


    The graph looks like this:
    Code:
            |                   *
            |               *
            |           *
            |       *
            |   *
           2*
            |
            |
        - - + - - - - - - - - - - -
