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:
F(x)=(x-3)(x+8)(x-11)=0
(x-3)=0, (x+8)=0, (x-11)=0
X=3
X=-8
X=11
Answer:
1) 57 seconds
2) 28 feet
Step-by-step explanation:
Factoring method.
D 2x + 28 = 48
because x + x + 14 + 14 equals the perimeter which is 48
