Question

Find the value of
(Sin30/ cos45) +(tan 45 / sec 60) -(cos30/tan45) - ( sin 60/ sin 90)

Answer 1

sin30=1/2
cos45=1/√2
tan45=1
sec60=2
cos30=√3/2
sin60=√3/2
sin90 =1

By putting these values in your question, we will get,

= (1/2 / 1/√2)+(1/2)-(√3/2 / 1)-(√3/2 / 1)
= (√2/2)+(1/2)-(√3/2)-(√3/2)
= (√2+1-2√3)/2

This cannot be simplified further, thx for asking, HAPPY TO HELP
