3. What are the coordinates of the points of tangency of the two tangent lines through the point (1,1) each tangent to the circl
VashaNatasha [74]

Answer:y+x=2    

Step-by-step explanation:

Given

equation of circle x^2+y^2=1

Equation of tangent passing through (1,1)

Slope of tangent is given by differentiating equation of circle

2x+2y\frac{\mathrm{d} y}{\mathrm{d} x}=0

\frac{\mathrm{d} y}{\mathrm{d} x}=\frac{-x}{y}

at (x,y)=(1,1)

\frac{\mathrm{d} y}{\mathrm{d} x}=\frac{-1}{1}

Equation of line with slope

m=\frac{y-y_0}{x-x_0}

-1=\frac{y-1}{x-1}

y+x=2

I just need answers to the odd numbered questions.<br> I would appreciate the help<br><br> 35 points
Misha Larkins [42]

Answer:

Step-by-step explanation:

Combine real terms and combine complex terms

1) 3 + 2i + 2 - 5i = 3 +2 + 2i - 5i

                          = 5 + (2-5)i

                          = 5 + (-3)i

                          = 5 - 3i

3) 2 - (1 - 2i) + (4 -5i ) - (1 - 3i)  = 2 -1 + 2i + 4 - 5i - 1 + 3i

           {- is distributed to (1 - 2i) & - is distributed to (1- 3i)}

              = 2 - 1  + 4 + 1 + 2i - 5i + 3i

              = 6 +0i = 6

5) 4 - 3i + 4 + 3i = 4 +4 -3i + 3i

                          = 8

7) (3 - 2i)² + (3 +2i) = 3² - 2*3*2i + (2i)² + 3 + 2i     {(a - b)² = a² - 2ab +b²}

= 9 -12i + 4i² + 3 + 2i

= 9 - 12i + 4*(-1) + 3 + 2i       {i²  = -1}

= 9 +3 - 4 - 12i +2i

= 8 - 10i

9) (a +b)^{4} - (a - b)^{4} = 8ab(a^{2} +b^{2})\\\\\\Here, \ a = 1 \ and \ b = i\\\\\\(1+\sqrt{-1})^{4}-(1-\sqrt{-1})^{4}=(1+\sqrt{i^{2}})^{4}-(1-\sqrt{i^{2}})^{4}\\\\=(1+i)^{4}-(1-i)^{4}\\\\=8*1*i(1^{2}+i^{2})\\\\=8i*(1 -1)\\\\=8i*0\\\\=0
