Answer:

Step-by-step explanation:

so i cant put an answer for some reason but here it is: when dividing fractions you would need to multiply to solve. The easyist way to do so from the ways i learned is keep change flip. so keep: 2/3 change a divide to a multiplication simbol and flip 1/4 to 4/1 so your left with G: 2/3 x 4/1

hope that helps btw if you need me to explain more let me know whats confusing you so i can help!!

HELP FAST PLEASE!!!!!

Alright, lets get started.

The answer Sandra got is correct that is zero but there are some mistakes she made while writing steps.

2 cot(\frac{-9\pi}{2})  =  2 cot(\frac{9\pi}{2}) Incorrect step

Because as per even/odd identity,

Cot (-Θ) = - cot (Θ)

Hence

2 cot (\frac{-9\pi}{2}) = - 2 cot (\frac{9\pi}{2})

Now,

It could be written as

-2 cot (\frac{9\pi}{2}) =   -2 cot (\frac{\pi}{2})


-2 * 0

0

Hence the answer is 0. : Answer

Hope it will help :)
