Simplify the following expression. cot^2x secx-cosx

Solnce55 [7]

ANSWER

$\cos(x) \cot ^{2} (x)$

EXPLANATION

The given expression is;

$\cot^{2} (x) \sec(x) - \cos(x)$

Change everything to

$\sin(x)$

and

$\cos(x)$

This implies that,

$\frac{ \cos^{2} (x) }{ \sin^{2} (x) } \times ( \frac{1}{ \cos(x) } )- \cos(x)$

Cancel the common factors,

$\frac{ \cos(x) }{ \sin^{2} (x) } \times ( \frac{1}{1} )- \cos(x)$

$\frac{ \cos(x) }{ \sin^{2} (x) }- \cos(x)$

$\frac{ \cos(x) - \sin ^{2} (x) \cos(x) }{ \sin^{2} (x) }$

$= \frac{ \cos(x)(1 - \sin ^{2} (x) ) }{ \sin^{2} (x) }$

$= \frac{ \cos(x)(\cos^{2} (x) ) }{ \sin^{2} (x) }$

$= \cos(x) \cot^{2} (x)$

Question 9 Annabelle lives at Bermondsey in London. She has to speak at a conference in Birmingham at 10.30am. It will take her

JulijaS [17]

Answer:

Step-by-step explanation:

working backwards

the five minute walk

10:30 - 0:05 = 10:25

train ride to Birmingham

10:25 - 1:10 = 9:15

Next earliest train departure time

9:05

Getting to Euston Station

9:05 - 1:00 = 8:05 am

Probably wise to leave a couple of minutes earlier to allow for minor emergencies on the way to Euston Station or to account for potential clock synchronization errors.

The train schedule already allows an additional 10 minutes of buffer time after boarding.

Evaluate the 1/3 of 10.25

Gala2k [10]

$\textsf{Hey there!}$

$\textsf{The word OF means MULTIPLY in mathematical terms }$

$\mathsf{So, \ your\ equation\ becomes: \dfrac{1}{3}\times 10.25 }$

$\mathsf{You\ can\ convert\ \dfrac{1}{3}\ into\ a\ decimal\ and\ solve\ from \ there}$ $\textsf{(if you want to)}$

$\mathsf{\dfrac{1}{3} \times 10.25=3.416667}$

$\boxed{\textsf{Thus your answer is: \boxed{\huge\text{\bf{3.416667}}}}}}\checkmark$

$\textsf{Good luck on your assignment and enjoy your day!}$
