Solution:


Given:

k1 = sec^θ(1 - sinθ)(1 - sinθ)


To Find:

Value of k


Approach:

We know that secθ = 1/cosθ

Therefore, k1 can be written as:

k1 = (1/cosθ)(1 - sinθ)(1 - sinθ)

k1 = (1 - sinθ)(1 - sinθ)/cosθ

k1 = (cos²θ)/cosθ - 2sinθ(cosθ)/cosθ + sin²θ

k1 = cosθ - 2sinθ + sin²θ/cosθ


Let's simplify the expression:

k1 = 1/cosθ - 2sinθ/cosθ + sin²θ/cosθ

k1 = secθ - 2tanθ + tan²θ


As we know that secθ = 1/cosθ and tanθ = sinθ/cosθ, the expression can be written as:

k1 = secθ - 2sinθ/cosθ + (sinθ/cosθ)²

k1 = secθ - 2sinθ/cosθ + sin²θ/cos²θ

k1 = secθ - 2sinθ/cosθ + (1 - cos²θ)/cos²θ

k1 = secθ - 2sinθ/cosθ + 1/cos²θ - 1

k1 = (secθ + tanθ)² - 1


Therefore, the value of k is:

k = (secθ + tanθ)² - 1 - k1


Answer:

The value of k is (secθ + tanθ)² - 1 - k1.
