Schritte zur Lösung

Apply the Maclaurin Formula

= 0 + \frac{\frac{d}{d x} ( sin ( \frac{x π}{4} ) ) ( 0 )}{1 !} x + \frac{\frac{d ^{2}}{d x ^{2}} ( sin ( \frac{x π}{4} ) ) ( 0 )}{2 !} x^{2} + \frac{\frac{d ^{3}}{d x ^{3}} ( sin ( \frac{x π}{4} ) ) ( 0 )}{3 !} x^{3} + \dots

Evaluate Derivatives

= 0 + \frac{\frac{π}{4}}{1 !} x + \frac{0}{2 !} x^{2} + \frac{- \frac{π ^{3}}{64}}{3 !} x^{3} + \frac{0}{4 !} x^{4} + \frac{\frac{π ^{5}}{1024}}{5 !} x^{5} + \frac{0}{6 !} x^{6} + \frac{- \frac{π ^{7}}{16384}}{7 !} x^{7} + \frac{0}{8 !} x^{8} + \frac{\frac{π ^{9}}{262144}}{9 !} x^{9} + \dots
