Find the equation of the line tangent to the graph of y equals cos2x at x equals pi divided by 4?
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 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.
32 x 32 x 32?
32 cubed equals to 32768.
What is x plus 32 equals 55?
x + 32 = 55 x = 55 - 32 x = 23
