Important relationships to note:

sec(x) = 1/cos(x)
cot(x) = 1/tan(x)
cosec(x) = 1/sin(x)

Thus, we can say:
sec(x) · tan(x) · sin(x) = [sin(x) · tan(x)]/cos(x)
= tan(x) tan(x)
= tan^2(x)

Answer:

StartFraction 2 plus or minus StartRoot (negative 2) squared minus 4(1)(negative 3) EndRoot Over 2(1) EndFraction

Step-by-step explanation:

General quadratic equation: ax^2 + bx + c

where a is the coefficient of the quadratic term, b is the coefficient of the linear term and c is the independent term. Here the equation is: x^2 – 2x – 3, so a = 1, b = -2 and c = -3

Quadratic formula:

$x = \frac{-b \pm \sqrt{b^2-4(a)(c)}}{2(a)}$
