HELP FAST PLEASE!!!!!
lidiya [134]

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 :)

The table shows a student's proof of the quotient rule for logarithms.
nikklg [1K]

Answer:

The error is at step (3) .

The correct step (3) will be,

\log_{b}(\frac {b^{x}}{b^{y}})

= \log_{b}(b^{x - y})   [by using the laws of indices]

All other steps are correct.

Step-by-step explanation:

The error is at the step (3) , because the student has tried to prove the quotient rule of logarithms by using the property i.e., 'The quotient rule of logarithm' itself , i.e. ,by  assuming the property does hold before proving it. So, the proof is fallacious.

The correct step (3) will be,

\log_{b}(\frac {b^{x}}{b^{y}})

= \log_{b}(b^{x - y})   [by using the laws of indices]

All other steps are correct.
