Answer:
Depends on what it is
Step-by-step explanation:
I can't tell you because I don't know what we are comparing. :)
Remember:
sec t=1/cos t
sin²t+cos²t=1 ⇒sin²t=1-cos² t
Therefore:
cos t(sec t- cost)=(cos t* sec t)- cos² t=(cos t * 1/cos t)-cos² t=1-cos²t=sin² t
Answer: cos t(sec t-cos t)=sin² t
Answer: B
Step-by-step explanation: Always B
We can’t see the picture :( so we can’t do it
