How do I convert standard form to point slope
Fittoniya [83]

The point-slope form:

y-y_1=m(x-x_1)

(x_1,\ y_1) - given point

m - given slope

The standard form:

Ax+By=C


y-y_1=m(x-x_1)    <em>use distributive property</em>

y-y_1=mx-mx_1      <em>add y_1 to both sides</em>

y=mx-mx_1+y_1      <em>subtract mx from both sides</em>

-mx+y=-mx_1+y_1       <em>change the signs</em>

mx-y=mx_1-y_1

Simplify(5+2i)(1+3i)
hichkok12 [17]
(5 + 2i)(1 + 3i)

5 * 1 = 5

5 * 3 = 15i

2i * 1 = 2i

2i * 3i = 6i^2

So we have...

5 + 15i + 2i + 6i^2

5 + 17i + 6i^2

In order....

6i^2 + 17i + 5

Suppose F⃗ (x,y)=⟨ex,ey⟩F→(x,y)=⟨ex,ey⟩ and CC is the portion of the ellipse centered at the origin from the point (0,1)(0,1) to
Rudik [331]

Probably the intended ellipse is the one with equation

\dfrac{x^2}{49}+y^2=1

We can parameterize C as a piece of this curve by

\vec r(t)=\langle7\sin t,\cos t\rangle

with 0\le t\le\frac\pi2. Then

\displaystyle\int_C\vec F\cdot\mathrm d\vec r=\int_0^{\pi/2}\langle e^{7\sin t},e^{\cos t}\rangle\cdot\langle7\cos t,-\sin t\rangle\,\mathrm dt

etc
