The value of sin^2 90° + √2 cos 45° + √3 cot 30° is_____(a) 2(b

1.	The value of sin^2 90° + √2 cos 45° + √3 cot 30° is_____(a) 2(b) 0(c) 4(d) 5This question was posed to me in unit test.I want to ask this question from Trigonometric Ratios ofSpecific Angles in chapter Trigonometry of Mathematics – Class 10
Answer» CORRECT option is (d) 5 Explanation: sin^2 90° + √2 cos 45° + √3 cot 30° = 1^2 + √2 (\( \frac {1}{\SQRT 2}\))+ √3 (√3) = 1 + 1 + 3 = 5
