Aha

#

Found it

#

U did a error in the(( 2^1/2) / 2 )/4 thing

steel zealot
#

When you replaced the value for sin 135 degrees, instead of dividing it by 4 you brought it to the numerator

#

$\sin \theta = \frac{\frac{\sqrt{2}}{2}}{4}$

#

this turns to $\sin \theta = \frac{\sqrt{2}}{8}

#

$\sin \theta = \frac{\sqrt{2}}{8}$

i dont understand

#

i thought i did it right

#

@steel zealot

south dune
#

as u times the whoel fraction by 4/4

reef ivy
#

So basically root 2/2 is divided by 4/1 so it turns as root 2 /2 multiplied by 1/4

#

Well the denominator is considered as 4/1 just for ease of understanding

south dune
#

huh

#

i dont understand

#

like i get that u can flip the 4/1 and times it and that u get root2/8

#

but i dont get why what i did was wrong as well

#

because if u times the numerator and demoniator by 4 then its overal timesing by 1 so its fine

#

so why would it bwe wrong

#

thats the way i was taught to do it

#

@reef ivy

reef ivy
south dune
#

yes ik

south dune
#

but i dont understand why my method wwouldnt also work

reef ivy
#

So u can consider 4 as 4/1 so get flipped and multiplied

reef ivy
south dune
#

this is corerct?

#

Yes exactly treat the root 2 / 2 as numerator and 4 as denominator so multiply 4 in numerator and 4 in denominator

reef ivy
#

Not root 2 by 2/4

south dune
#

oh do u need brackets here?

reef ivy
south dune
#

ohhhhhh

#

so its wrong without brackets basically

reef ivy
south dune
#

why is this wrong then

reef ivy
#

To avoid division error which u did just now

south dune
#

the true answer is root 2 over 8

reef ivy
#

So u multiplied numerator with 4

#

Denominator becomes 16

#

It becomes 2 root 2 /16

south dune
#

how is 2 x 4 equaling 16

reef ivy
#

Ayo bro 😭

#

Treat root 2 by 2 as numerator

south dune
#

yea

reef ivy
#

So numerator multiply numerator

#

What do u get?

south dune
#

so it should be 4 root 2 / 2

reef ivy
#

Yess

#

Denominator multiply denominator

#

So 4x4 is 16

south dune
#

the donminator is 1 if its an integer of 4

#

wiat no i think i get it all now

#

u meant the other demointaror

#

hold on lemme show my workings

reef ivy
# south dune

No u had 4/1 in denominator so it gets flipped and multiplied in numerator

south dune
#

yea i got it right look

reef ivy
# south dune

So in this just flip 4/1 to 1/4 and there's ur answer

south dune
reef ivy
#

U got it

south dune
#

finally got it

#

thanks for ur help
