Question

Simplify cos2 Θ(1 + tan2 Θ). (2 points) Question 4 options: 1) cos2 Θ + sin2 Θ 2) cos2 Θ 3) 1 4) −1

Answer 1

answer:

3) 1 is the answer

Answer 2

Answer:

Option 1)cos2 Θ + sin2 Θ

Step-by-step explanation:

$cos2x(1+tan2x)\\cos2x(1+\frac{sin2x}{cos2x})\\cos2x(\frac{cos2x + sin2x)}{cos2x} \\cos2x +sin2x$

convert x to Θ
