Question

sin30/sin45+tan45/sec60-sin60/cot45-cos30/sin90


answer is 8√3
i want explaination​

Answer 1

Step-by-step explanation:

sin30° = 1/2 sin45° = 1/√2 sin60°= √3/2 sin90°= 1

cos30°=√3/2

tan45°=1

cot45°=1

sec60°=2

By putting these values we get

=1/2/1/√2 + 1/2 - √3/2/1 -√3/2/1

= √2/2 +1/2 - √3/2 - √3/2

= √2+1-√3-√3/2
