Please select the correct solution

• csc² x
• cot² x
• sin² x
• sec² x

Verify the following.
tanB (cotB + tanB) = sec²B

• 1+ tan²B
• sec²B
• cot²B
• tan²B

Please select the correct solution

• csc x
• sec x
• cot x
• tan x

Is this one of the identities we can use to prove/simplify other identities?

tan²x + 1 = secx

• Yes

• No

• (cos/sin)(sin/cos)

• cos

• sin

• (sin/cos)(cos/sin)

• (sinx /cosx) / ((cos x + sin x) / cos x))

• (sinx) / (sin x)

• (sinx) / (cosx)

• (cosx) / ((cos x + sin x) / cos x))

Which of the following would be a step to prove the following identity?

• (1/ sin x) - (1 / cos x)

• (cos x - sin x) / ( sin x)

• (cos x - sin x) / (cos x)

• (1/ sin x cos x)

• cot

• (1 / cos)

• tan

• (1 / sin)

Verify the following

• (1 + cosx) / (cos x)

• (1) / (sin x)

• (1 + sinx) / (sin x)

• (sinx) / (sin x)
