Arctangent(12.8/6.8)=

Arctangent(1.88235) =62.02 degrees.

The Law of Cosines says: c^2 = a^2 + b^2 − 2ab cos(C), where a, b, c are sides of the triangle, and A, B, C are angles opposite each side. The order of operations depends on what you are trying to calculate.

\(\cos=\frac{adjacent}{hypotnuse}\)

\(\cos{(\theta)}=\frac{\sin{(\theta)}}{\tan{(\theta)}}\)

FV=PV[1 + R ]^N

FV=2,599.68[1 + .05]^45

FV=$23,358.15

I meant:

\(\vec{a}= \begin{pmatrix} 5\\ 5\\ \end{pmatrix}\) 

instead of:

\(a= \begin{pmatrix} 5\\ 5\\ \end{pmatrix}\)

you don'tallways need to use it in terms of x.

sometimes a, t, d, even the consant sign: C, ext., it can be anything you would like.

this is pi:

pi: greek leter

use: tofind the circomfrence, ext.

notation: \(\pi\)

approxamation: \(\pi \approx 3.14159265\)

Square root=~3.60

So, it lies between 3 and 4

(d)/(dx)( integral_3^x e^t cos(t^3) dt) = e^x cos(x^3)
(d)/(dx)( integral_x^3 e^t cos(t^3) dt) = -e^x cos(x^3)

Solve for x:
6 x^2+13 x+11 = 0

Divide both sides by 6:
x^2+(13 x)/6+11/6 = 0

Subtract 11/6 from both sides:
x^2+(13 x)/6 = -11/6

Add 169/144 to both sides:
x^2+(13 x)/6+169/144 = -95/144

Write the left hand side as a square:
(x+13/12)^2 = -95/144

Take the square root of both sides:
x+13/12 = (i sqrt(95))/12 or x+13/12 = 1/12 (-i) sqrt(95)

Subtract 13/12 from both sides:
x = (i sqrt(95))/12-13/12 or x+13/12 = 1/12 (-i) sqrt(95)

Subtract 13/12 from both sides:
Answer: |  x = (i sqrt(95))/12-13/12     or      x = 1/12 (-i) sqrt(95)-13/12

the wheel of the car has an outer radius of 25 cm Calculate: How far the wheel traveled after one complete turn of wheel How many times the wheel turns for a journey of 1 km.

Cirumference=Diameter x Pi

25 x 2 = 50 cm-diameter of the wheel.

50 x 3.141592 =157.0796 cm-circumference of the wheel.

1 km x 1000 m x 100 cm =100,000 cm

100,000 / 157.0796 =636.620 Turns in 1 km journey.

Distance in one turn of the wheel = circumference = pi*50 cm

Number of turns in 1km = 100000/(50pi).   Because there are 100000 cm in 1km

1 + 1.1p - (1.5p - 1) = 4

-0.4p + 2 = 4

-0.4p = 2

p = 2/(-0.4)

p = -5

.

The dummy variable under the integral sign is t, but the integral itself is a function of x, and the derivative is taken with respect to x.

Imagine a simpler situation where you have d/dx of the integral from 0 to x of t with respect to t.

The integral would result in x^2/2, which, when differentiated wrt x would return x (not t).

6x+8=20

6x+8-8=20-8

6x=12

x=12/6

x=2

well, she is displaying it in terms of t.

48T=48T^2

T=T^2

T^2 - T=0

T(T - 1)=0

T=0 and

T=1

x-15% = 100

x = 100+15%

   = 100 + 3/20

   = 2003/20

   = 100.15
