Please select the correct solution

• csc² x
• cot² x
• sin² x
• sec² x

Please select the correct solution 
cos ² x + sin ² x=  

• 1
• csc ² x + sec ² x
• sin ² x
• 1 - sin ² x

Please select the correct solution

• csc x
• sec x
• cot x
• tan x

Is this a pythagorean identity?
tan²x + 1 = secx

• Yes
• No

cot²θ=

• sec²θ - 1
• 1 - cos²θ
• csc²θ - 1
• 1 - sin²θ
