sin^3(x)+sin(x)=2sin^{22}(x)

الحلّ

sin^{3} (x) + sin (x) = 2 sin^{22} (x)

الحلّ

x = 2 πn, x = π + 2 πn, x = \frac{π}{2} + 2 πn

درجات

x = 0^{\circ} + 36 0^{\circ} n, x = 18 0^{\circ} + 36 0^{\circ} n, x = 9 0^{\circ} + 36 0^{\circ} n

خطوات الحلّ

sin^{3} (x) + sin (x) = 2 sin^{22} (x)

بالاستعانة بطريقة التعويض

sin^{3} (x) + sin (x) = 2 sin^{22} (x)

sin (x) = u :

على افتراض أنّ

u^{3} + u = 2 u^{22}

u^{3} + u = 2 u^{22} : u = 0, u = 1

u^{3} + u = 2 u^{22}

بدّل الأطراف

2 u^{22} = u^{3} + u

انقل

إلى الجانب الأيسر

2 u^{22} = u^{3} + u

من الطرفين

اطرح

2 u^{22} - u = u^{3} + u - u

بسّط

2 u^{22} - u = u^{3}

2 u^{22} - u = u^{3}

انقل

u^{3}

إلى الجانب الأيسر

2 u^{22} - u = u^{3}

من الطرفين

اطرح

2 u^{22} - u - u^{3} = u^{3} - u^{3}

\frac{1 + tan ^{2} ( x )}{1 + sec ( x )} = sec (x)

-sin^2(x)+2cos(x)-2=0

- sin^{2} (x) + 2 cos (x) - 2 = 0

sin(5x-1)= 4/5

sin (5 x - 1) = \frac{4}{5}

sin^2(x)= 1/36

sin^{2} (x) = \frac{1}{36}

tan(x)=31

tan (x) = 31
