Prove the trigonometric identity
Annette [7]

Answer:

Proved See below

Step-by-step explanation:

Man this one is a world of its own :D Just a quick question are you a fellow Add Math student in O levels i remember this question from back in the day :D Anyhow Lets get started

For this question we need to know the following identities:

1+tan^{2}x=sec^2x\\\\1+cot^2x=cosec^2x\\\\sin^2x+cos^2x=1

Lets solve the bottom most part first:

1-\frac{1}{1-sec^2x} \\\\

Take LCM

1-\frac{1}{1-sec^2x} \\\\\frac{1-sec^2x-1}{1-sec^2x} \\\\\frac{-sec^2x}{1-sec^2x} \\\\\frac{-(1+tan^2x)}{-tan^2x}

now break the LCM

\frac{-1}{-tan^2x}+\frac{-tan^2x}{-tan^2x}\\\\\frac{1}{tan^2x}+1\\\\cot^2x+1

because 1/tan = cot x

and furthermore,

cot^2x+1\\cosec^2x

now we solve the above part and replace the bottom most part that we solved with cosec^2x

\frac{1}{1-\frac{1}{cosec^2x} } \\\\\frac{1}{1-sin^2x} \\\\\frac{1}{cos^2x}\\\\sec^2x

Hence proved! :D

8 to 11 do it with equations thx
Alenkasestr [34]

Answer:

Step-by-step explanation:

8. 4\geq x+\frac{3}{4}

4(4\geq x+\frac{3}{4} )

16\geq 4x + 3

-3         -3

13\geq 4x

\frac{13}{4}\geq \frac{4x}{4}

\frac{13}{4} \geq x = x\leq \frac{13}{4}

x\leq \frac{13}{4}=3.25

9. x-3\leq -8

       +3     +3

x\leq -5}

10. 4\leq x-7

  +7         +7

11\leq x=x\geq 11

11. 6.9 < x - 2.3

 + 2.3      + 2.3

 9.2 < x = x > 9.2

Hope this helps!
