Question

evaluate sin 30+ tan 45- cosec 60/cot 45+cos 60-sec 30

Answer 1

hey
here's your answer!!

sin 30+ tan 45- cosec 60/cot 45+cos 60-sec 30

sin 30 = 1/2
tan 45 = 1
cosec 60 = 1/(√3/2) = 2/√3
cot 45 = 1
cos 60 = 1/2
sec 30 = 1/(√3/2) = 2 /√3

1/2 + 1 - (2/√3)/1 + 1/2 - 2 /√3
= 1 + 1 - 4/√3
= 2 -4/√3 (answer)

Answer 2

Sin 30=1/2,tan 45=1/√2,cosec60=2/√3,cot 45=1,cos60=1/2,sec 30=2/√3
1/2+1/√2-2/√3/1+1/2-2/√3
