Cos theta x
WebMay 3, 2016 · 3. If x is strictly considered to be a natural number, then there is using imaginary numbers in its derivation. Euler's formula states that e i α = cos ( α) + i sin ( α). Now, consider α = θ n for some natural number n. The function ℜ ( z) is defined as the real part of an imaginary number z, and so ℜ ( a + i b) = a. WebWe know that the maximum value of a cos θ + b sin θ + c is c + ( a 2 + b 2). Substituting a = 13 2, b = - 3 √ 3 2 and c = 3, we get, The maximum value = 3 + 169 4 + 27 4 = 3 + 7 = 10. Hence, Option ( C) is the correct answer. Suggest Corrections.
