# Is TANX COSX Sinx an identity?

## Is TANX COSX Sinx an identity?

Because the two sides have been shown to be equivalent, the equation is an identity.

## What is TANX COTX?

tanx + cotx = sinx/cosx + cosx/sinx = ( sin^2 x + cos^2 x )/sinx cosx.

Is Sinx an identity?

Identities involving trig functions are listed below….

Odd/Even Identities
sin (–x) = –sin x cos (–x) = cos x tan (–x) = –tan x csc (–x) = –csc x sec (–x) = sec x cot (–x) = –cot x

What is TANX Sinx equal to?

Each of these functions are derived in some way from sine and cosine. The tangent of x is defined to be its sine divided by its cosine: tan x = sin x cos x . The cotangent of x is defined to be the cosine of x divided by the sine of x: cot x = cos x sin x .

### What is sinx COSX and TANX?

tan x = sin x cos x . The cotangent of x is defined to be the cosine of x divided by the sine of x: cot x = cos x sin x . The secant of x is 1 divided by the cosine of x: sec x = 1 cos x , and the cosecant of x is defined to be 1 divided by the sine of x: csc x = 1 sin x .

### What is the difference between SiNx and cosx Siny?

sinX cosY = (1/2) [ sin (X + Y) + sin (X – Y) ] cosX sinY = (1/2) [ sin (X + Y) – sin [ (X – Y) ] sinX sinY = (1/2) [ cos (X – Y) – cos (X + Y) ] Difference of Squares Formulas

What is the formula for tan tan x + π?
