what is integral of cos?
The indefinite integral of cos(x) is sin(x) + C, and we can find the definite integral of cos(x) between two limits by evaluating sin(x) + C at the upper and lower limits and subtracting the results.
The integral of cos(x) is sin(x) + C, where C is the constant of integration.
The notation for the integral of cos(x) is ∫cos(x) dx, where the symbol ∫ represents the integral sign, cos(x) is the function being integrated, and dx represents the variable of integration, which in this case is x.
The antiderivative of cos(x) is sin(x), meaning that if we take the derivative of sin(x), we get cos(x). The constant of integration, C, is added because the derivative of a constant is always zero.
Therefore, the indefinite integral of cos(x) is sin(x) + C, and we can find the definite integral of cos(x) between two limits by evaluating sin(x) + C at the upper and lower limits and subtracting the results.

What is the gradient of the surface?
The gradient of the surface can be described as a vector.
The gradient of a surface, which is a vector, represents the size and direction of the sharpest increase in value at a certain location. The magnitude of this vector, which denotes the direction of the greatest rate of rise of the surface, indicates how steep the rise is. The influence of this gradient is felt along a surface, which is the difference. It stands in for a unit that is level with the ground.
In mathematics, the vector grad f(x,y,z) = (df/dx, df/dy, df/dz) represents the gradient of a three-variable function with scalar values, f(x,y,z). Variables like optimization and electromagnetism employ the gradient of a surface, which is a crucial notion in vector calculus. In particular, the gradient of a surface is frequently used to compute the normal vector to a surface or to identify the direction of the steepest rise or drop in a landscape.

What is an equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions written on the left and right sides. We have LHS = RHS (left-hand side = right-hand side) in every mathematical equation. To determine the value of an unknown variable that represents an unknown quantity, equations can be solved. A statement is not an equation if it contains no "equal to" symbol. It will be regarded as a phrase.
Given that
x⁻¹/(x⁻¹ + y⁻¹) + x⁻¹/(x⁻¹ - y⁻¹) = 2y²/(y² - x²)
Now solve the left-side expression:
L.H.S =
x⁻¹/(x⁻¹ + y⁻¹) + x⁻¹/(x⁻¹ - y⁻¹)
Now apply the formula a⁻¹ = 1/a:
= (1/x)/(1/x +1/y) + (1/x)/(1/x - 1/y)
= (1/x)/((x+y)/xy) + (1/x)/((y-x)/xy)
Now taking common (1/x)/(1/xy):
= (1/x)/(1/xy)[1/(x+y) + 1/(y-x)]
= (xy)/(x)[(y - x + x + y)/(x+y) (y-x)]
= y[2y/(x+y) (y-x)]

The three sides of a triangle (triangle 2) measure a = 18. 5 in, b = 12. 2 in, and c = 50. 6 in. What are the three internal angles: α, β, and θ?
The three internal angles of the triangle are α = 21.3°, β = 139.7°, and θ = 88.9°.
We can use the Law of Cosines to solve for the angles of the triangle:
cos(α) = (b² + c² - a²) / (2bc)
cos(β) = (a² + c² - b²) / (2ac)
cos(θ) = (a² + b² - c²) / (2ab)
Substituting the values given in the problem, we get:
cos(α) = (12.2² + 50.6² - 18.5²) / (2 x 12.2 x 50.6) = 0.929
α = cos⁻¹(0.929) = 21.3°
cos(β) = (18.5² + 50.6² - 12.2²) / (2 x 18.5 x 50.6) = -0.777 (note the negative value)
β = cos⁻¹(-0.777) = 139.7°
cos(θ) = (18.5² + 12.2² - 50.6²) / (2 x 18.5 x 12.2) = 0.056

The slope of a line that is parallel to the line containing the points (3, 4) and (2, 6) is -2.
What is the slope of a line that is parallel to the line containing the points (3, 4) and (2,6)?To find the slope of a line that is parallel to the line containing the points (3, 4) and (2, 6), we first need to find the slope of the line containing these points. We can use the slope formula:
m = (y2 - y1) / (x2 - x1)
Where:
m = slope
(x1, y1) = coordinates of the first point (3, 4)
(x2, y2) = coordinates of the second point (2, 6)
Substituting the given values, we get:
m = (6 - 4) / (2 - 3)
m = -2
The slope of the line containing the points (3, 4) and (2, 6) is -2.
Since we are looking for a line that is parallel to this line, the slope of the parallel line will also be -2.

Eight upright domino's of increasing heights are lined up to be knocked down. The dominos are numbered 0 to 7. The smallest domino, #0 is 5.00 cm tall and will be toppled by a person to start the chain reaction. Each subsequent domino is 13% taller than the one before. What is the height of domino number 7?
The required height of domino number 7 is 11.76 cm (rounded to two decimal places).
What is arithmetic progression?Arithmetic progression is the series of numbers that have common differences between adjacent values.
Here,
Since each subsequent domino is 13% taller than the one before, we can find the height of each domino by multiplying the height of the previous domino by 1.13.
Starting with the height of the smallest domino, we can calculate the height of each subsequent domino using this rule:
Height of domino n = Height of domino (n-1) × 1.13
Using this formula, we can find the height of each domino:
Height of domino 1 = 5.00 cm × 1.13 = 5.65 cm
Height of domino 2 = 5.65 cm × 1.13 = 6.38 cm
Height of domino 3 = 6.38 cm × 1.13 = 7.21 cm
Height of domino 4 = 7.21 cm × 1.13 = 8.16 cm
Height of domino 5 = 8.16 cm × 1.13 = 9.22 cm
Height of domino 6 = 9.22 cm × 1.13 = 10.41 cm
Height of domino 7 = 10.41 cm × 1.13 = 11.76 cm
Therefore, the height of domino number 7 is 11.76 cm (rounded to two decimal places).

What other observation can you make about the number pattern?
Answer:
Step-by-step explanation:
256. You can make this observation because they pattern has a rule that you multiply by 2 to get the next number.
Answer:
Another observation we can make about this number pattern is that each term is obtained by doubling the previous term. This means that the pattern is an example of exponential growth, where the growth factor is 2.
We can also observe that the sequence is a power of 2, where the first term is 2^2, the second term is 2^3, the third term is 2^4, and so on. In other words, the nth term in the sequence can be represented by the formula 2^(n+1).
Additionally, we can see that the sequence is an increasing sequence, where each term is greater than the previous one. This is because we are multiplying each term by 2, which means that each subsequent term will be twice as large as the previous one.
