Question

2 tan²45°+cos²30°-sin²60°

Answer 1

Answer:

$2 {(1)}^{2} + {( \frac{ \sqrt{3} }{2} }^{2} - { \frac{1}{2} }^{2} \\ 2 + \frac{3}{4} - \frac{1}{4} \\ \frac{8 + 3 - 1}{4} \\ \frac{10}{4} \\ \frac{5}{2 }$

Answer 2

Answer:

2

Step-by-step explanation:

2tan^2 45° + cos^2 30° - sin^2 60°

=> 2(1)^2 + (√3/2)^2 - (√3/2)^2

=> 2×1

=> 2
