Question

if tita=45 deg ,find value of 2cosec sq tita+3sec sq

Answer 1

The final answer is 10
Explanation:
Theta = 45°
$2cos^{2}$ (theta)+$3sec^{2}$ (theta)
=$2cos^{2}$ (45°)+$3sec^{2}$ (45°)
=2 $\sqrt{2}^{2}$ +$3 \sqrt{2}^{2}$
=2 × 2+ 3 ×2
=4+6
=10

Answer 2

Tita = 45°
2cosec^2 (tita)+3sec^2 (tita)
=2cosec^2 (45°)+3sec^2 (45°)
=2 (root2)^2 +3(root2)^2
=2×2+3×2
=4+6
=10
