Question

15. Find the value of followings
(i) tan 60° - cot 30° + sec 30°​

Answer 1

tan (60o) = √3 cos(45o) = 1/√2 sec(30o) = 2/√3 cos(90o) = 0 cosec (30o) = 2 sec (60o) = 2 cot (30o) = √3 Now putting the values, we get = 9/

evaluate-the-following-

tan-2-60-4cos-2-45-3sec-2-30-5cos-2-90-cosec30-sec60-cot-2-30

Answer 2

i hope -1 is right answer
