    For the first one, do what jonmack did by substituting v = x - y + 3. When you take the derivative of both sides this equation
    dv/dx = 1 - dy/dx.

    So,

    v = x - y + 3 and dy/dx = 1 - dv/dx ...

    sec^2(x) - 4 = 0

    Use the secant/tangent Pythagorean identity:
    (sec x)^2 = (tan x)^2 + 1

    So,
    [(tan x)^2 + 1] - 4 = 0
    (tan x)^2 - 3 = 0
    (tan x)^2 = 3
    sqrt(tan^2(x)) = +/-sqrt(3)
