Question

cot30/sec30+cosec30/tan45-2cos0/sin30+cos^245

Answer 1

Answer:

-1/2 is the answer..

Step-by-step explanation:

cos30°=√3

sec30°=2/√3

cosec30°=2

tan45°=1

cos0°=1

sin30°=1/2

cos45°=1/√2

Substitute the above given values in the equation:

=√3/(2/√3)+[2/1-2(1)/(1/2)]+(1/√2)^2

=3/2+[2/-1/(1/2)]+1/2

=(-1)/2

Please make me the brainliest is my answer is correct.
