brave patio number 10 explain someone plseasde?

How else can you express sin(90 - x)

brave patio Sep 28, 2023, 11:48 PM

#

1-sinx?

latent jasper Sep 28, 2023, 11:49 PM

#

4cos(3ϴ) - sin(90 - 3ϴ) -> 4cos(3ϴ) - cos(3ϴ) = 3cos(3ϴ)

brave patio Sep 28, 2023, 11:50 PM

#

how’s it cos 30?

latent jasper Sep 28, 2023, 11:51 PM

#

it's 3 theta

brave patio Sep 28, 2023, 11:51 PM

#

yeah

#

but

latent jasper Sep 28, 2023, 11:51 PM

#

Do you know the identity sin(90 - x) = cos(x)

brave patio Sep 28, 2023, 11:51 PM

#

no

latent jasper Sep 28, 2023, 11:51 PM

#

Well

brave patio Sep 28, 2023, 11:51 PM

#

now I do

#

sin(90-x) = cos(x)

#

sin(90-3(theta)) = cos(30)

#

latent jasper Well

I THINK I GOT IT

#

THANKS

#

one more question @latent jasper

#

WHAT I DO PART B

#

3 cos(30) =2?

latent jasper Sep 28, 2023, 11:56 PM

#

Do you know about the unit circle?

brave patio Sep 28, 2023, 11:56 PM

#

latent jasper Do you know about the unit circle?

Or math teacher mentioned it

#

But I didn’t understand
