#1

anyone know how to do this?

#2

It's a secret.

#3

well i'm assuming you know that Pi as a fraction is 22/7?

#4

Take the sqrt of both sides:

sin(t)=√3/2

You can take it from there.

sin(t)=√3/2

You can take it from there.

I hope to god you're being sarcastic.

#6

T = Tits. Works for me.

#7

It's either pi/3 or pi/6. Can't remember which, and I can't be arsed to draw out the special right triangle for that case.

Yeah, it's pi/3 (60 degrees).

On the interval 0-360, it can be 60 or 120 degrees. Both give a value of 0.866, via CAST rule.

EDIT: To summarize:

Square root both sides, then sin t = (sqrt 3)/2

The 30 60 90 triangle has side lengths 1, sqrt 3, and 2, and by drawing it you can see that sin 60 will give (sqrt 3)/2.

CAST rule says that sin will be positive in quadrants 1 and 2, so we find that both 60 and 180-60 will give a value of (sqrt 3)/2.
