solvefor c,sin^3(x)+sin(x)cos(x)+cos^3(x)=1

Lösung

löse nach

c, sin^{3} (x) + sin (x) cos (x) + cos^{3} (x) = 1

Wahr f \overset{u}{¨} r alle c; sin^{3} (x) + sin (x) cos (x) + cos^{3} (x) = 1

Schritte zur Lösung

sin^{3} (x) + sin (x) cos (x) + cos^{3} (x) = 1

Beide Seiten sind gleich

Wahr f \overset{u}{¨} r alle c; sin^{3} (x) + sin (x) cos (x) + cos^{3} (x) = 1

so l v e f or t, tan (x) tan^{2} (x) = 1

so l v e f or t, tan (a) + tan (b) = 2 tan (a + b)

so l v e f or t, tan (b) = sin (a) cos (\frac{a}{2}) + cos^{2} (a)

so l v e f or c, cos^{2} (x) - 4 sin (x) + 2 cos (x) - 3 = 0

so l v e f or f, (a + f) = a \cdot cosh (\frac{l}{( 2 a )})
