0.5
What is the number and type of roots of the equation x2-4x-32 equals 0?
There are 2 roots to the equation x2-4x-32 equals 0; factored it is (x-8)(x+4); therefore the roots are 8 & -4.
How do you find the equation of a tangent line to the graph of fx equals x cubed and x equals -2?
Calculate the derivative of the function.Use the derivative to calculate the slope at the specified point.Calculate the y-coordinate for the point.Use the formula for a line that has a specified slope and passes through a specified point.
If x varies jointly as y and the square as z and x equals 40 when y equals 20 and z equals 2 find x when y equals 30 and z equals 3?
As x ∝ yz2 then x = kyz2 where k is a constant. Substituting the given figures, 40 = k*20*22 = 80k Then k = ½ and the formula is, x = ½yz2 So, x = ½ * 30 *32 = 135
What is inverse tangent?
It is a function which maps the tangent ratio - any real value - to an angle in the range (-pi/2, pi/2) radians. Or (-90, 90) degrees.If tan(x) = y then x is the inverse tangent of y.It is also known as "arc tangent", and spreadsheets, such as Excel, use "atan" for this function.Warning:1/tangent = cotangent is the reciprocal, NOT the inverse.
How do you put cotangent in a TI-84 calculator?
The TI-83 does not have the cot button, however, if you type 1/tan( then this will work the same as the cot since cot=1/tan. The other way to do this is to type (cos(x))/(sin(x)) where x is the angle you're looking for. This works because cot=cos/sin
What is tangent 25 equals 7 divided by x?
x = 15.01, approx.
Cotangent squared plus one equals cosecant squared?
yes 1 + cot x^2 = csc x^2
How does cot multiplied to cosec equals cos?
The statement "cot multiplied by cosec equals cos" is not accurate. In trigonometric terms, cotangent (cot) is the reciprocal of tangent, and cosecant (cosec) is the reciprocal of sine. Therefore, the correct relationship is ( \cot(x) \cdot \csc(x) = \frac{\cos(x)}{\sin^2(x)} ), which does not simplify to cosine. Instead, it highlights the relationship between these functions in terms of sine and cosine.
What is -x equals 32?

Find the equation of the line tangent to when x equals 8?
The question is suppose to read: Find the equation of the line tangent to y=(x²+3x)²(2x-2)³, when x=8
What is contangent?
The cotangent, often abbreviated as "cot," is a trigonometric function defined as the ratio of the adjacent side to the opposite side in a right triangle. It can also be expressed as the reciprocal of the tangent function: ( \cot(x) = \frac{1}{\tan(x)} = \frac{\cos(x)}{\sin(x)} ). The cotangent function is periodic with a period of π radians. It is commonly used in various fields, including mathematics, physics, and engineering.
