It is known that the minimum integer solution of inequality 2 (x + 1) - 5 ＜ 3 (x-1) + 4 is the solution of the equation 1 / 3 x MX. Find the value of the quadratic-2m-11 of the algebraic formula M
2x+2-5
Simplified radical 1-2sin130 ° cos130 ° / sin130 ° + radical 1-sin ^ 2130 ° =?
√(1-2sin130°cos130°)/[sin130°+√(1-sin^2130°)]=|sin130°-cos130°|/(sin130°-cos130°)=1
X squared - 4x + 3 = 0
x^2-4x+3=0
(x-1)(x-3)=0
x1=1,x2=3
sin70°cos25°-cos70°sin25°=
sin(A-B)=sinAcosB-cosAsinB
sin(70-25)
=sin45=1/√2
Direct use of sum difference formula
The original formula is sin (70 ° - 25 °) = sin 45 ° = 1 / √ 2
sin（A-B)=sinAcosB-cosAsinB
Application of the formula.
Sin45 = root 2 / 2
3 / 4x-5% x = 17.5
3 / 4x-5% x = 17.5
0.75x-0.05x=17.5
0.7x=17.5
x=25
sin70°cos25°-sin25°cos70°
This is the inverse of the formula sin (a-b) = sin acosb cos asinb
sin70°cos25°-sin25°cos70°
=sin(70°-25°)
=sin45°
=√2/2
The root of two is two
From the sum angle formula sin (a + b) = sinacosb + cosasinb (Rewriting B to - B has sin (a-b) = sinacos (- b) + cosasin (- b) = = sinacosb cosasinb)
knowable
Sin70 ° cos25 ° - sin25 ° cos70 ° = sin45 ° = root 2 / 2
I hope my answer can help you ~ you can ask me if you don't understand~
sin70cos25-cos70sin25
=sin(70-25)
=sin45
=Root of two
sin70°cos25°-cos70°sin25°
=sin（70°-25°）
=Sin45 ° = two half root sign 2
4X + 8 (17-x) = 10, solve the equation!
Wrong. Sorry, 4x + 8 (17-x) = 100
4X+136-8X=100
-4X=-36
X=9
Sin70 ° cos25 ° - sin ° sin25 ° is equal to
sin70°cos25°-sin20°sin25°
=sin70°cos25°-cos70°sin25°
=sin(70°-25°）
=sin45°
=√2/2
sin°sin25？
It's like something's missing?
God knows
How does the sin20 ° in the middle of sin (70 ° - 25 °) turn into cos 70 °? The induction formula SiNx = cos (90-x) can be brought in x = 20, sin20 ° is equal to Cos 70 ° ah
Solving equation x square = - 4x
X = 0 or - 4
-4
X = 0 or x = minus 4
X^2=-4X
X^2 4X=0
X(X 4)=0
X1=0,X2=-4
X squared = - 4x
x²+4x=0;
x(x+4)=0;
X = 0 or x + 4 = 0;
X = 0 or x = - 4;
