<span>cos t(sect- cos t)
sec t = 1/cos t so
= cos t( 1/cos t - cos t)
= cos t / cos t - cos²t (distribute)
= 1 - cos²t
since sin²t + cos²t = 1, we have sin²t = 1 - cos²t
so
= sin² t
=right-hand side

Answer: -4
Step-by-step explanation:
The outcome is negative since -16 is bigger than 12.
If you do the math then you will get -4
Test contains 10 three-point questions and 14 five-point questions.
Normally you would divide something like this by the cuts made. So if there were cuts of 2 inches on a 10 inch rope, then you should divide 10 by 2. It's the same with this:
![5/ \frac{1}{3} = 5*3, 15 \ pieces](https://tex.z-dn.net/?f=5%2F%20%5Cfrac%7B1%7D%7B3%7D%20%3D%205%2A3%2C%2015%20%5C%20pieces)
Multiply by the reciprocal when you are dividing fractions.
