Question

Find the general Solution of cos o
-​

Answer 1

Answer:

Similarly, general solution for cos x = 0 will be x = (2n+1)π/2, n∈I, as cos x has a value equal to 0 at π/2, 3π/2, 5π/2, -7π/2, -11π/2 etc.

Answer 2

Step-by-step explanation:

θ = 2nπ ± ∝, where n ∈ Z. Hence, the general solution of cos θ = cos ∝ is θ = 2nπ ± ∝, where n ∈ Z. Note: The equation sec θ = sec ∝ is equivalent to cos θ = cos ∝ (since, sec θ = 1cosθ and sec ∝ = 1cos∝).
