Which statement is correct?
1 answer:
Answer:
B. Cosecant is the reciprocal of sine
Step-by-step explanation:
Well, this is where you have to remember your reciprocal identities in your trigonometric identities!
So:
- Cosecant is the reciprocal of sine
- Secant is the reciprocal of cosine
- Cotangent is the reciprocal of tangent
How I remember them is just the co is with the non-co (cosecant with sine (no co there) and cosine with secant. Tangent with cotangent is pretty easy to remember.)
I'll attach a picture for trig identities! Let me know if you have any further questions :)
