Find all degree solutions. (Enter your answers as a comma-separated list. Let k be any integer.)2 cos2 4𝜃 + 3 cos 4𝜃 + 1 = 0
Question
Solution 1
This equation is a quadratic in terms of cos(4θ). We can solve it by using the quadratic formula, which is x = [-b ± sqrt(b^2 - 4ac)] / (2a). Here, a = 2, b = 3, and c = 1.
Step 1: Calculate the discriminant (b^2 - 4ac) = (3)^2 - 4*(2)*(1) = 9 - 8 = 1
Step 2: Substitute a, b, and the discriminant Knowee AI is a powerful AI-powered study tool designed to help you to solve study problem.
