Question

find the value of question​

Answer 1

Answer:

sinacosd /secucosecu

Answer 2

Step-by-step explanation:

$\sf \frac{sin\alpha}{sec4\alpha} + \frac{cos\alpha}{cosec4\alpha} \\ \\ \sf \longrightarrow \frac{sin\alpha}{\frac{1}{cos4\alpha}} + \frac {cos\alpha}{\frac{1}{sin4\alpha}} \\ \\ \sf \longrightarrow sin\alpha.cos4\alpha + cos\alpha.sin4\alpha \\ \\ \sf \longrightarrow sin(\alpha + 4\alpha ) \\ \\ \sf \longrightarrow sin(5\alpha)$
