Given Equation is 2sin²x + 3cosx = 0
⇒ 2(1 - cos²x) + 3cosx = 0
⇒ 2 - 2cos²x + 3cosx = 0
⇒ 2cos²x - 3cosx - 2 = 0
⇒ 2cos²x - 4cosx + cosx - 2 = 0
⇒ 2cosx(cosx - 2) + (cosx - 2) = 0
⇒ (2cosx + 1)(cosx - 2) = 0
⇒ cosx - 1/2, cosx = 2[Not possible]
⇒ cosx = -1/2
⇒ x = 120°,240°
⇒ x = (2π/3) + 2πn, x = (4π/3) + 2πn

For e.g. the range of the function F is {1983,1987,1992,1996}. On the other hand, the whole set B is known as the codomain of the function. It is the set which contains all the outputs of the function. So, the set of real numbers is a codomain for every real-valued function. The codomain of the function F is set B.

However, the sudden outbreak of the novel coronavirus in the country and the nationwide lockdown imposed in order to contain the virus postponed a few exams.

Global Minima & Maxima of f(x) in [a, b] is the least or the greatest value of the function f(x) in interval [a, b].
1. The function f(x) has a global maximum at the point ‘a’ in the interval I if f (a) ≥ f(x), for all x ∈ I.
2. Function f(x) has a global minimum at the point ‘a’ if f (a) ≤ f (x), for all x ∈ I.
