Question

tan² 60 - cot² 45 +2 cos² 60 ÷ 3​

Answer 1

Answer:

1/2

Step-by-step explanation:

Tan 60 = √3

Cot 45 = 1

Cos 60 = 1/2

So,

tan² 60 - cot² 45 +2 cos² 60 = $\sqrt[]{3} ^{2}$ - $1^{2}$ + 2($\frac{1}{2^{2} }$) = 3 - 1 + $\frac{2}{4}$ = 2 - $\frac{1}{2}$  = $\frac{3}{2}$

now,

tan² 60 - cot² 45 +2 cos² 60 ÷ 3​ = $\frac{\frac{3}{2}}{3}$ = $\frac{3}{3.2}$ = $\frac{1}{2}$
