x2 = beta / 2 + alpha = [ 3 + sqrt ( 17 ) ] / ( 2 * 2 ) + [ 3 - sqrt ( 17 ) ] / 2 = [ 3 + sqrt ( 17 ) ] / 4 + 2 * [ 3 - sqrt ( 17 ) ] / ( 2 * 2 ) ] = [ 3 + sqrt ( 17 ) ] / 4 + 2 * [ 3 - sqrt ( 17 ) ] / ( 2 * 2 ) = [ 3 + sqrt ( 17 ) ] / 4 + [ 6 - 2 sqrt ( 17 ) ] / 4 = [ 3 + sqr...

The zeroes of the polynomial x ^ 2 - 3 x - 2 are [ 3 - sqrt ( 17 ) ] / 2 [ 3 + sqrt ( 17 ) ] / 2 so: alpha = [ 3 - sqrt ( 17 ) ] / 2 beta = [ 3 + sqrt ( 17 ) ] / 2 x1 = alpha / 2 + beta = [ 3 - sqrt ( 17 ) ] / ( 2 * 2 ) + [ 3 + sqrt ( 17 ) ] / 2 = [ 3 - sqrt ( 17 ) ] / 4 + 2 *...

cos ^ 2 ( x ) - sin ^ 2 ( x ) = 2 cos ^ 2 ( x ) - 1 Subtract cos ^ 2 ( x ) to both sides cos ^ 2 ( x ) - sin ^ 2 ( x ) - cos ^ 2 ( x ) = 2 cos ^ 2 ( x ) - 1 - cos ^ 2 ( x ) - sin ^ 2 ( x ) = cos ^ 2 ( x ) - 1 Add 1 to both sides - sin ^ 2 ( x ) + 1 = cos ^ 2 ( x ) - 1 + 1 1 - ...
