## 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?**

**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
