Question

if tan theta=1/2 then find the value of 2 cot²theta +2
please its urgent​

Answer 1

$\tan \: theta \: = \frac{1}{2}$

$2 \cot ^{2} (theta) + 2$

$= 2 ({ \frac{1}{ \tan } )}^{2} + 2$

$= 2 \times 4+ 2$

$= 8 + 2$

$10$

Answer 2

Answer:

given that : tanθ = 1/2

to find value of : 2 cot²θ + 2

we know that cotθ= 1/tanθ

so, 2(1/tan)²+2

=2(1/2)² +2

=2×1/4+2

=2×4+2

=8+2

=10
