Sinx plus cosx equals 0?
x = 3pi/4
What is 3pi to the nearest whole number?
3pi to the nearest whole number
What is a secant of a circle?
a secant is a line containing a chord. A secant is a line that intersects the circle twice(or passes through a circle)
What is the trigonometric function sec?
The function sec(x) is the secant function. It is related to the other functions by the expression 1/cos(x). It is not the inverse cosine or arccosine, it is one over the cosine function. Ex. cos(pi/4)= sqrt(2)/2 therefore secant is sec(pi/4)= 1/sqrt(2)/2 or 2/sqrt(2).
1 over cos x equals what?
sec(x)=1/cos(x), by definition of secant.
Given the polar coordinate 2 square root of 2 and 3 pi over 4 what is the equivalent Cartesian coordinate?
x = 2 sqrt(2) cos(3PI/4) y = 2 sqrt(2) sin(3PI/4) cos(3PI/4) = -1/sqrt(2) sin(3PI/4) = 1/sqrt(2) Therefore, the Cartesian coordinates are: x= -2 sqrt(2) / sqrt(2) = -1 y = 2 sqrt(2) / sqrt(2) = 1 (-1,1) is the corresponding Cartesian coordinate.
What is an secant in math?
Secant is a trignometric function. In a right triangle, the secant of an angle is the hypotenuse over the adjacent side. It is also the inverse of cosine. For example secant(x) = 1/cos(x)
Why dont you have buttons for cotangent secant cosecant?
You don't have buttons for cotangent, secant, and cosecant because you don't need them. Just invert. Cotangent is 1 over tangent, secant is 1 over sine, and cosecant is 1 over cosine.
Sinx plus cosx equals 0?
x = 3pi/4
How do you find sec on TI-83 Plus?
There isn't a sec key on the TI-83 Plus. Secant is 1/cosine, which is what is used to find secant on a TI-83 Plus. For example, to find the secant of 4, enter 1/sec(4).
What is 3pi to the nearest whole number?
3pi to the nearest whole number
Can you help solve the equation w equals 3 pi StartRoot StartFraction x Over t EndFraction EndRoot for the variable x Assume all other letters represent nonzero constants?
w=3pi*sqr(x/t) First divide each side by 3pi w/3pi=sqr(x/t) Next square both sides. (w/3pi)^2=x/t Next multiply both sides by t t(w/3pi)^2=x
What is secant pi over 6?
It is 2*sqrt(3)/3.
What is the volume of a spherical water tank that is 18 feet in diameter?
Volume = 4/3*pi*radius cubed V = 4/3pi r^3 your radius is 18 feet/2 = 9 feet V = 4/3pi(9 feet )^3 = 3054 cubic feet in volume
What is the measure of a secant CD If ab is 14 and bd is 4?
18
Does trignometry secant relate to circles secant?
yes
Is 3pi a rational irrational natural whole integer or real number?
Since pi is an irrational number, then 3pi will be an irrational also.
