  1. sin(- 22 .5) =-sin( 22 .5) Using the half-angle identity sin^2( 22 .5) = (1-cos(45))/2 = (1-(1/sqrt(2)))/2 = (sqrt(2)-1)/2sqrt(2) = (2-sqrt(2))/4 = sin(- 22 .5) = -(1/2)sqrt(2-sqrt(2))

  4. here's the rule you need: log(m^n) = n · log(m) log(7^x) =log( 22 ) -> x · log(7) = log( 22 ) x · log(7)/log(7) = log( 22 )/log(7) x = log( 22 )/log(7)
