y = tan-1(x / a) dy/dx = a / (a2 + x2)
y = cot-1(x / a) dy/dx = - a / (a2 + x2)
y = sec-1(x / a) dy/dx = a / (x (x2 - a2)1/2)
y = cosec-1(x / a) dy/dx = - a / (x (x2 - a2)1/2)

Can someone please explain the area of a circle in the simplest way possible, no links
Answers
So, for the area of a circle, there should be a line in the middle. Correct?
Well, that line is the diameter. Then cut that in half, so if the diameter is 6, the radius is 3.
Then multiply the the radius by the radius, so 3x3 once you get that, multiply the answer by pi. Pi= 3.14, so if you do 3x3x3.14 you should get 28.26. Hope this helps.

Step-by-step explanation:
a (length of the telephone pole) = 9m
b (distance between the pigeon and the pole) = 3m
c = ?
According to the Pythagorean theorem,
a² + b² = c²
9² + 3² = c²
81 + 9 = c²
c² = 90
c = 9.4m
∴ the pigeon will fly 9.4m

What are the dimensions of the rectangle?
A rectangle has an area of 40 square units. The length
is 6 units greater than the width
O 8 by 5
10 by 4
11 by 9
13 by 7
Answers
Answer:
its b
Step-by-step explanation:
The requried dimensions of the rectangle are 10 by 4. Option B is correct.
What is a rectangle?The rectangle is 4 sided geometric shape whose opposites are equal in lengths and all angles are about 90°.
Here,
To solve the problem, we can use the formula for the area of a rectangle, which is:
area = length x width
We also know that the length is 6 units greater than the width, which we can express as:
length = width + 6
We can substitute this expression for length into the formula for area, giving us:
area = (width + 6) x width
area = width² + 6width
We are given that the area is 40 square units, so we can set up the equation:
40 = width² + 6width
We can rearrange this equation into the standard quadratic form:
width² + 6width - 40 = 0
We can then use the quadratic formula to solve for the width:
width = (-b ± √(b² - 4ac)) / 2a
Plugging in the values of a, b, and c from the quadratic equation above, we get:
width = (-6 ± √(6² - 4(1)(-40))) / 2(1)
width = (-6 ± √(196)) / 2
width = (-6 ± 14) / 2
So we have two possible values for the width:
width = (-6 + 14) / 2 = 4
or
width = (-6 - 14) / 2 = -10
Since the width cannot be negative, we can reject the second solution. Therefore, the width of the rectangle is 5 units.
We can use the expression for the length in terms of the width to find the length:
length = width + 6 = 4 + 6 = 10
Therefore, the dimensions of the rectangle are 10 by 4.
