Question
What is the primary responsibility of the "Controller"
in the MVC architecture?Solution
The "Controller" in the MVC architecture manages the user interaction and application flow. It receives user input from the "View," processes it, interacts with the "Model" to update or retrieve data, and determines how the application should respond based on the input and data.
If 6sin²x + 2cos²x − 3 = 0, then find the value of sinx, given that 0° < x < 90°.

If tan 4θ = cot 14θ, then find the value of cos 9θ.
- If sin(A + B) = 1/2 and cos(A + 2B) = 1/√2, where 0° < A, B < 90°, then find the value of tan(2A).
- Find the maximum value of (12sin A + 16cos A).
If sec 4A = cosec (3A - 50°), where 4A and 3A are acute angles, find the value of A + 75.
If sec x + tan x = 11 then find secx?
If sec A + tan A = 7 and sec A - tan A = (1/7), find the value of cos A.
