Card 1 of 20

The reciprocal identity for cosecant is csc⁡x=\csc x =cscx= [...]\text{[...]}[...].

A

The reciprocal identity for cosecant is csc⁡x=\csc x =cscx= 1sin⁡x\boxed{\frac{1}{\sin x}}sinx1​​.

B

Zeros of an original trig function become vertical asymptotes of its reciprocal graph.

C

In terms of sine and cosine, cot⁡x=\cot x =cotx= cos⁡xsin⁡x\boxed{\frac{\cos x}{\sin x}}sinxcosx​​.

D

Secant is even: sec⁡(−x)=\sec(-x)=sec(−x)= sec⁡x\boxed{\sec x}secx​.
