प्रश्न

Find the principal solutions of the following equation:

cot θ = 0

योग

उत्तर

cot θ = 0

Since θ ∈ (0, 2π)

∴ cot θ = 0 = cot `π/2 = "cot" (π + pi/2)`   … [∴ cot (π + θ) = cot θ]

∴ cot θ = cot `π/2 = cot  (3π)/2`

∴ `θ = pi/2  or  θ = (3π)/2`

Hence, the required principal solutions are `{π/2, (3π)/2}`.
