What is the value of sin square 30+ tan square60-sec square 60 + cosec square 30+ cosec square 45+sec square 30-cot square 45 - tan square 30

Answer 1

Answer:

ur ans

Step-by-step explanation:

(tan^2 60+4cos^2 45 + 3sec^2 30+5cos^2 90) ./(cosec 30 + sec 60 - cot^2 30)

={(√3)^2 + 4×(1/√2)^2 + 3×(2/√3)^2+ 5×0^2} /{2+2-(√3)^2

={(3+4×(1/2) +3×(4/3)+0)}/(4–3)

=3+2+4=9
