I didnt get how you proof x=y, jyu.anywayIf you draw whole circle it will be easy to se how to solve and as you wrote the aswer will be 1/4
symmetry on both sides of z.jyu
Rotate everything by β/2 clockwise. Then all calculations become vertical and horizontal.For example:x = sqrt(4-cos(β/2)^2) - 2*sin(β/2)z = sin(β/2)Therefore cos(β/2) = sqrt(5/8)cos(β/2)^2 = 5/8 = (1 + cos(β/2))/2cos(β) = 1/4
can you solve this problem simpler and more understandable, thnx

ReplyDeleteFor example:
x = sqrt(4-cos(β/2)^2) - 2*sin(β/2)
z = sin(β/2)
Therefore cos(β/2) = sqrt(5/8)
cos(β/2)^2 = 5/8 = (1 + cos(β/2))/2
cos(β) = 1/4
can you solve this problem simpler and more understandable, thnx
