Answer 1

Answer:

• Sequence: b >> a >> d

Step-by-step explanation:

The steps are as below:

• $sec^2x - tan^2x = 1$
• $1/cos^2x - sin^2x/cos^2x = 1$
• $(1 - sin^2x)/cos^2x = 1$
• $cos^2x/cos^2x = 1$
• $1=1$

Answer 2

• sec²x-tan²x
• 1/cos²x-sin²x/cos²x
• 1-sin²x/cos²x
• cos²x/cos²x
• 1

The order is

• b,a,d
