Question

cosec-67 – tan23 =___________​

Answer 1

Answer:

-0.662 (approx)

Step-by-step explanation:

Sol. cosec-67 - tan23

= -cosec67-tan23

= -cosec(90-23)-tan23

= -sec23-tan23

= -(1-sin23)/cos23

= -0.661885561

= -0.662 (approx)

Answer 2

Answer:

cosec 67 = 1/tan67

1/tan 67 = tan23

cosec 67 = tan 23

cosec67 - tan 23 = 0
