Question
Which operation is NOT part of relational
algebra?Solution
Update is SQL DML, not relational algebra.
- If (tan 4x · tan x = 1), then find the value of (tan 5x).
If √3 tan x = 3, then the value of x:
- Simplify the following trigonometric expression:
sin 2A + sin 2B Find the maximum value of (20sin A + 15cos A).
If 4sin² θ = 3(1+ cos θ), 0° < θ < 90°, then what is the value of (2tan θ + 4sinθ - secθ)?
If tan A = 1/√3, then what will be the value of sin⁴ A?
If sin(3θ) = cos(2θ), then find the value of θ between 0 and 90 degrees.
tan 20˚ x tan 23˚ x tan 67˚ x tan 70˚ = ?
- If X = 15°, find the value of:
sin²(3X) + cos²(4X) - tan²(2X) If sec(2A + B) = 2 and cos(A + B) = (1/√2) , find the value of {sec 2B + tan (A + B) } given that 0o < A, B < 90o
