Solve the equation for theta, giving a general formula for all of the solutions: sin(theta/2)=1/2

the question is solve the equation for theatre giving a general formula for all the solution to is equals to 1 by 2 sin theta minus sin theta opposite side by side will be 2nd edition will be one divided all the angles one square will be one and two squirrel before and cut it don't want but it won't and you a square square the year 1 Square One the answer will come answer will come 3 root answer is 3 root if you want some cases contact me

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this
