Question

find the value sin²60⁰+tin²45⁰/cosec²30⁰​

Answer 1

Question:

Find the value of $\frac{ \ {sin}^{2} 60 + \ {tan}^{2} 45}{\ {cosec}^{2} 30}$

Answer:

$\frac{ \ {sin}^{2} 60 + \ {tan}^{2} 45}{\ {cosec}^{2} 30}$

Now, putting the value from trigonometry table

$\frac{ \frac{3}{4} + 1 }{4}$

$\frac{ \frac{3 + 4}{4} }{4}$

$\frac{ \frac{7}{4} }{4}$

$\frac{7}{4} \div 4$

$\frac{7}{4} \times \frac{1}{4}$

$\frac{7}{16}$

0.4375

Therefore, $\frac{ \ {sin}^{2} 60 + \ {tan}^{2} 45}{\ {cosec}^{2} 30}$ = 0.4375
