Algebra.Com's Answer #761732 by greenestamps(13203)![]() ![]() You can put this solution on YOUR website! \n" ); document.write( "(1) sin(x)=1 at x = pi/2 + k(2pi) \n" ); document.write( "4 theta = pi/2 + k(2pi) --> theta = pi/8 + k(pi/2) \n" ); document.write( "(2) By looking at \"nice\" angles, we can find that this equation is satisfied by an angle of (3/2)pi +k(pi). The other solutions can only be found by numerical methods. \n" ); document.write( " \n" ); document.write( " |
