What is the range of y equals sin2x?

range of y=sin(2x) is [-1;1]

and in generally when is y=sin(k*x) (k=....-1,0,1....) range is always [-1;1] and the period is w=(2pi)/k

What is cot theta 1.5 sin theta?

The expression "cot theta = 1.5 sin theta" can be rewritten using the definitions of trigonometric functions. Since cotangent is the reciprocal of tangent, we have cot(theta) = cos(theta) / sin(theta). Therefore, the equation becomes cos(theta) / sin(theta) = 1.5 sin(theta), leading to cos(theta) = 1.5 sin^2(theta). This relationship can be used to find specific values of theta that satisfy the equation.

How do you prove that the derivative of sec x is equal to sec x tan x?

Show that sec'x = d/dx (sec x) = sec x tan x.

First, take note that

sec x = 1/cos x;

d sin x = cos x dx;

d cos x = -sin x dx; and

d log u = du/u.

From the last, we have du = u d log u.

Then, letting u = sec x, we have,

d sec x = sec x d log sec x; and

d log sec x = d log ( 1 / cos x )

= -d log cos x

= d ( -cos x ) / cos x

= sin x dx / cos x

= tan x dx.

Thence, d sec x = sec x tan x dx, and

sec' x = sec x tan x,

which is what we set out to show.

What are tangent tables used for?

tangent tables are used to find values of all angles..precisely..like tan 15 degress and 25 minutes.

What does sine era mean?

Sine ira means "without anger".

What is trigonometric leveling?

It is the process of determining the differences of elevation of stations from observed vertical angle and known horizontal distance..

How do you solve a set?

You cannot solve a set You may be able to solve some questions about properties of a set, or the set and another set. But a set, by itself, is not something that requires or can be "solved".

How do you graph y equals cotangent 5?

If angles are measured in radians, the graph consists of the set of points (0.1974+k*pi, 5) where k is an integer. If they are measured in degrees, the points are (11.31+k*180, 5)

Where did the word cobra come from?

From Port. cobra (de capello) "serpent (of the hood)," from L. colubra "a snake," of uncertain origin. The word came to Eng. via Portuguese colonies in India, where the native name is nag.

Cos2x equals 1 minus tan squared x divide by1 plus tan squared x?

The Answer is 1 coz, 1-Tan squarex = Cot square X. So cot square x divided cot square x is equal to 1

How do you find the exact value of tan 165?

tan x = sin x / cos x

sin x = x - (x^3/3!) + (x^5/5!) - (x^7/7!) + (x^9/9!) ... to infinity

cos x = 1 - (x^2/2!) + (x^4/4!) - (x^6/6!) + (x^8/8!) .. to infinity

tan 165 degrees = -0.267949192

What is a hectagon?

A Heptagon is a 7 sided polygon.

A Hectagon is a 100 sided polygon.

The spell check says it's not spelled correctly, but it is.
