Question

EVALUATE:
cos 45°/sec 30° + cosec 30°.​

Answer 1

Answer:

$\huge \mathfrak \purple{put \: the \: values}$

$\frac{1}{ \sqrt{2} } \div \frac{2}{ \sqrt{3} } + 2 \\ \\ = \frac{1}{ \sqrt{2} } \times \frac{ \sqrt{3} }{2} + 2 \\ \\ = \frac{ \sqrt{3} \times \sqrt{2} }{2 \sqrt{2} \times \sqrt{2} } + 2 \\ \\ = \frac{ \sqrt{6} }{4} + 2 \\ \\ = \frac{8 + \sqrt{6} }{4}$

Answer 2

Answer:

cos 45°/sec 30° + cosec 30°

= (1/√2)/(2/√3) + 2

=√3/2√2  + 2

= (√3+ 4√2) / 2√2
