Question

if anyone can answer my question given in this picture ​

Answer 1

Answer:

Step-by-step explanation:

sin 90 =1

cos 90 =1

tan 60 = $\sqrt{3}$

cot 30 = 1/$\sqrt{3$

$sin^{2} 90 * cos^{2} + tan^{2} 60 * cot^{2} 30.\\1^{2} *1^{2} +sqrt{3} ^{2} *(1/sqrt{3} )^{2} \\1*1 + 3+(1/3)\\1+10/3\\14/3$

Answer 2

Answer:

please see my dp

Answer:

Step-by-step explanation:

sin 90 =1

cos 90 =1

tan 60 = \sqrt{3}

cot 30 = 1/\begin{lgathered}\sqrt{3\\\end{lgathered}

\begin{lgathered}sin^{2} 90 * cos^{2} + tan^{2} 60 * cot^{2} 30.\\1^{2} *1^{2} +sqrt{3} ^{2} *(1/sqrt{3} )^{2} \\1*1 + 3+(1/3)\\1+10/3\\14/3\end{lgathered}
