pretty sure its a level

#

What are the constraints for theta?

earnest kestrel
#

Huh really

orchid fractal
#

is the question sin(2theta +30) = root3/2?

obsidian raft
earnest kestrel
#

Yes

orchid fractal
#

thats in year 1 of the a level course

#

never seen or done that in gcse lol

rancid stratus
#

could be further maths gcse

#

that's not in the reg spec tho for sure

earnest kestrel
#

All I know is that the 2 theta + 30 is equal to 60°

orchid fractal
#

nah I did further maths gcse aqa and it wasnt in the specification

How..

orchid fractal
#

theres more than 1 solution for theta btw

Like what are the possible solutions from 0 to 720

Oh

orchid fractal
#

you forgot the +30

earnest kestrel
#

So um like what's the answer then

earnest kestrel
#

Is the 30 supposed to be degrees

vapid beacon
#

If theta is in degrees then yes

#

The question should say if its degrees or radians

#

Do sin inverse then solve for theta..?
I’m not sure if that’s correct

sinx=root3/2

x=60

2x+30=60
x=15

x=theta
