Answer 2

The value of the expression is $\tan^245+\cot^230=4$

Step-by-step explanation:

Given : Expression $\tan^245+\cot^230$

To find : The value of the expression ?

Solution :

Expression $\tan^245+\cot^230$

We know the trigonometric values,

$\tan45=1$ and $\cot 30=\sqrt{3}$

Substitute,

$\tan^245+\cot^230=(\tan 30)^2+(\cot 45)^2$

$\tan^245+\cot^230=(1)^2+(\sqrt3)^2$

$\tan^245+\cot^230=1+3$

$\tan^245+\cot^230=4$

Therefore, the value of the expression is $\tan^245+\cot^230=4$
