If secθ - cosecθ = 0 and θ is an acute angle, then what is the value of sec2θ + cosec2θ ?
If \(x^2 + (4 - \sqrt{3})x - 1 = 0\) , then what is the value of ?
\(9 - 8\sqrt{3}\)
\(21 - 12\sqrt{3}\)
\(21 - 8\sqrt{3}\)
\(17 - 8\sqrt{3}\)
Simplify the following expression.
\(5\tfrac{1}{3} \div \left[7 - 3 \div \left(1 - \tfrac{1}{4}\right) \times \tfrac{2}{3} + 1\right] - 3 \div 1 + 2\)
